If i had $100 and couldn't keep it

If i had $100 that i couldn't keep i would give it to charity. I would donate the money most likely for cancer research. there is a girl going into the 4th or 5th grade that i do colorguard with (we used to be in the same group but she is younger so i moved up) who literally just found out she has cancer. A few other of my family members have been affected by cancer too so i feel that would be the best place to donate the money.
