My DS's best friend moved in 3rd grade. It was very tough on both boys. They are now in 5th and still talk on the phone and e-mail. AND - guess who's going all the way across the country for their vacation this year so the boys can have a reunion? We never thought we'd make it to North Carolina from Washington state, but dh's sister's family is stationed in Virginia Beach right now so we couldn't pass up the opportunity to get the boys back together.
I'm so excited for them to see each other, but worried too. It won't be the same and I'm afraid that they'll be disappointed.
