I have to say, the "not raised that way" doesn't hold much water with me. I was not raised that way, but it is really not that hard a thing to learn!
I suppose this is aimed at me, as I mentioned I was not raised this way. I did my darnedest as a young adult to observe my friends' manners and habits, and try to emulate them. Honestly, I had so so SO little growing up (except difficulties and heartache) that I could very well be the very MOST grateful person ever. I just have been teaching myself, through my adult life. I did send Thank You's after my wedding...I learned calligraphy, and penned them carefully. Each one personal. I got insulted, slammed, and made fun of. In fact, family war broke out over it and never resolved to this day. Apparently, many people consider handwritten Thank You's cheap and tacky.
It somewhat makes me sad, that so many on here are actually insulting those who don't write Thank You's. Some of us have been learning, and overcoming, for years. Nice to know that until we get it completely right, we've just been wasting our time.
I don't equate a lack of Thank You Note to ungratefulness, I have been moved to actual tears at generosity,a few times in my life. Sadly, it was before I'd heard of Thank You notes. I am so glad those people are not lashing out at me, for my "ungratefulness."
Really, I don't even know where I intended to go with this. Just wanted to mention that although my manners are apparently deplorable, my heart is good...and always has been. I don't send Thank You notes, but I do hold doors, say Please and Thank You, RSVP to parties, and try to never EVER arrive anywhere late. When invited to someone's home, I never arrive empty-handed, leave the leftovers when I leave....am I wasting my time with all those attempts at manners?
But when my friend threw my baby shower, I didn't send her a Thank You for doing so. Hopelessly mannerless.
