I have two adult children. We were a very close family. They live an hour and a half away. What can I do, neither will call or email.?

maybe you should check up on them, they could be in the hospital for all you know and cant call or email

You left this kind of vague! When you say they don't call or email, have you initiated anything? In many cases, everything boils down to communication. If you have expectations that they "should" do this, and so you don't do anything on your end, this could just be bad communication.

Also, how often do you see them? 90 minutes isn't much, and if they see you fairly often, they may not feel the need. When you say they're adults, are they young ones having fun with friends? In college? That's a lot different than kids in late 20's or early 30's, with their own family now and running in circles.

What matters most is WHY they aren't doing it, and you just didn't give enough info to guess at that. The other possibility, of course, is that your family wasn't as close as you thought. That seems unlikely, though.

Bottom line: It sounds like you need to talk to them about this.

you can call them

write them a letter and say "enjoy this gift card so you and your friends can go out to dinner together" but don't include the gift card. They will def call asking where the gift card is.

Facebook or snd a care package

Go and visit them - or aren't your children worth 90 minutes of your time?
