DEAR ABBY: I love my daughter-in-law and I am afraid she is harming herself because of her addiction to tanning. Her boys are in high school and cannot remember their mother without a really dark tan.

DEAR ABBY: I'm 18, and I'm leaving for college this fall. My boyfriend "Matt" will be attending community college nearby.

I want to live the next four years to the fullest. So, I want to be single so I can have a good time and be a little reckless without worrying about him.
