...my mother knew how to use the computer and email and all, but my in-laws didn't.
We gave them our PC (too big to lug to China anyway) and taught them how to use it. We succeeded in teaching my mother-in-law a future basic things, such as email. But they are so intimidated by it, that they rarely use it!
We'll go for weeks and not hear from them, unless we go buy a phone card and call them (they also can't figure out how to make international calls).
