Blackmailing

When I was 13 a friend of mine take me a picture when I was in the shower, I was unable to catch her as she ran out of the house (she stole my towel too) The next day she showed m the picture @ a lot of copies of it, she tod me that if I want the picture all over the school, I'll have to be her slave for the weekend, the most humilliating thing she ordered me to do ws to serve lemonade to our neighbor in my bathing suit! So I did, I felt terrible, I never talked to her ever since, but at least she kept her word & returned me the photo & all the copies she had
