What does she like to do?
I spent my summers as a teen swimming and reading and writing (some of my favorite things ever).
I had friends that went to camp (either as campers our CITs or counselors)
I had friends who went on an archeological dig
I had friends who got jobs
I had friends who played music/ learned an instrument
I had friends who joined the ROTC
Basically.... starting from bar / bat mitzvah age everyone had to figure out what they *loved* doing, and figure out a way to make it happen. $ to pay for it, transportation, etc. It's GREAT life skill training... the whole "You will be responsible for your life this summer. How do you want to spend it? Okay, let's figure it out."
