Obviously, you didn't read the whole letter. They did try to contact him, by cards, letters and e-mails and he never responded to them. Not only did they send gifts, but also helped him with educational and travel opportunities.

It is to much to ask for a simple "thank-you" or to even respond to them when they write.

I just don't understand why people think it's such a burden to say "Thanks for thinking of me." or "Thanks, I received the gift--it was nice." or "Thanks for the gift--but I don't like that color or it was too small, etc."

You talk about courtesy, but feel that the kid should just forget about that.

If anything, it's due to laziness on his part.
