True - 8 does seem to be a strange to have a phone. As a parent of a pre-teen girl (age 11), however, I make her take her phone everywhere. She's had it since she was 10. This way I know I can get in touch with her when she is out riding bikes with friends, etc. It just seems safer for her to have it than not.
AMEN!! Even with a cell tower semi close by I can't make a call my house on most days. There was a lady walking around in the $1 store the other day on her phone and she was saying "can you hear me now?" over and over. I had to laugh.
When I was pregnant, my husband would say "E=MC2" into my belly. To this day my now 6 year old will just say it out of nowhere. She has no idea what it means. I wish he had told her something a little more useful to remember.
