well i found a lost friend.
she was one of my dearest friend, we knew each other since 2nd grade. she was like a big sister to me, so overprotective of me, treated me like a baby.
but in the 6th grade, she started having problem with her mother and family. terrible problems. so she had to get away, and i heard she moved with her father, but then there were more problems. so she left, and i didn't know where, i asked her brother but he wouldn't tell me nothing.
for 4 years i wonder where was she, i was scared for her, until the friday before last friday. i saw her and i was so shocked to see her. she had tattoos on her back and a piercing below her bottom lip, and she was with a guy, her boyfriend i'm sure, and his family. and she was holding a little baby boy. i was so shocked. i couldn't believe she did this to herself.
i wanted to say hey and hug her, telling her i miss her so much, but i was so shocked after i saw her, i wanted to cry.
i think she waved hello to me but i'm not sure, i didn't wave back.
its been bothering me ever since. i don't know what to do. it really hurt me to see her like that. what she did with her body.and the baby boy. i'm hoping that isn't her.. son..
i don't know what to do. please help.
