Ok, here's my pixie dust moment, bear with me, it might be long:
3 years ago I took a LOOOONG be-all, get-all trip, alone to WDW - I had a CL suite, Platinum/Grand Plan for 30 days. That was a BIG mistake on my part - I refer to that trip as eating my way thru Disney.

Anyhow, it was very freaky weather for 2 days - it was 80, then it was 40, then it rained, then it got hot. When it rained it would be warm then chill down. Anyhow I got sick - bronchitis, sore throat, etc. Holed up in my suite for 4 days, not eating, just sleeping. I was so sick of being sick I asked the front desk to find me a pink grapefruit and the hottest horseradish around (homeopathic guaranteed remedy). They sent someone to Outback for horseradish and brought to my room, a bushel of Indian River grapefruit, no charge. I smeared the horseradish on the grapefruit, ate it, and the next day was fine and dandy. Unfortunately with something like 20 extra meals to use. SO I decided to spread the Disney pixie dust around and extend the kindness that Disney gave me to others - I picked up total strangers dinner and lunch tabs, anonymously.
Now you might believe the following is just a coincidence, and you may be right, BUT I believe everything happens for a reason and there are NO coincidences:
The last night I'm at the park and I still have 6 meals to use. I ate at Crystal Palace (it was the last seating for dinner) and they were booked solid, nobody else could get in. I see a young woman with a small boy about 3 outside looking in. She comes in and says she was meeting a friend. She sees me, eating alone, and says the smae thing that she's meeting friends but her son was tired so would I mind if they sat with me. Of course not I say and why didn't she and her son join me for dinner as my guests, that way when her friends arrive, they can enjoy the park together. She thanks me and they go up to the buffet. The plates they filled looked as though they hadn't eaten in days.
Meanwhile a man and woman and a young boy sit next to me at another table. Without meaning to, I overhear that they did not have enough money to pay for the dinner as the prices went up on Jan 2. I tell them I couldn't help but overhear and say they would be doing me a service if they allowed me to add their meals to my plan, which I'd already paid for and would lose otherwise. They tell me their son was in Make A Wish and their church raised the money to send them to Disney.
The young woman and her son come back to my table and I will say that the CM looked like he wanted to kill me when he saw me add all these meals to my card. I tippped him way beyond the standard 15%. The young woman asked what I did and I told her I was a fraud investigator. Let me just say that her face paled beyond that of the 999 ghosts at Haunted Mansion. I wondered, to myself, how she could afford the admission tickets to WDW. Then I saw the tickets were paper. I believe she fished them out of the trash can outside of the park, but I said nothing to her. I took a picture of her and her son with Pooh and with Piglet. I gave both parties my business card which had my email address on it. I never expected to hear from anyone.
I got an email last week from the young woman. She explained she had been running away from her abusive husband in Arizona who had threatened to kill her and her son. SO she drove to the Happiest Place on Earth - WDW. She said she had picked up one day tickets outside of the park that had been tossed. She was planning on conning her way for a meal for her son - they hadn't eaten in days. She now believes in magic and pixie dust and random acts of kindness and being honest and asking for and accepting help. She said if I hadn't been there and talked with her, she was sure she would have been arrested or that her husband would find them and she'd be dead. She went from WDW to a woman's shelter and hired a lawyer. SHe has sole custody of her son. SHe has a job and an apartment and she does random acts of pixie dust whenever she can. She said she is amzed at how a simple thing like buying a meal for someone can truly change their life.
As for the other family. They write me every Christmas - their son's cancer is in remission and they are quite happy.
So am I.
