Cell phones, I love them, I hate them!
Convenient when you have kids......
Me: Text me when you get there.
Them: Yes, mom
Them texting to Me: I'm here safe.

(of course you can't see the rolling of the eyes, but you KNOW they're doing it).
Me texting to Them: Text me when you leave, love you!
Them texting to Me: Yes, mom, love you!

(again, you can't see the rolling of the eyes, but you KNOW they're doing it again).
Instant messaging, I swear I talk to my daughter more now than before she left for college! Saves big time on phone bills.
Oh, and being able to call her computer and talk, it's great.
It's amazing how fast kids can text.
