Earlier today my friend took my bike to go to get some candy at dollar tree for her friend. I left it at the house so she used it to go there. She then left it outside the front doors without locking up the bike (She doesn't have a lock) When she looked outside someone was bolting off with my bike, she screamed after him and he kept going. She then called me and I don't know what to do? I can't tell my parents.
