My mom says "I been stealing money from her" because she's been blowing it on junk everyday(outside decorations, garden stuff etc) She always accuses somebody when she runs low on cash every month lol. Just cause I got child support and she doesn't know about it and won't lol. She doesn't know where I got money to buy things from. But it's been MY money. She's jealous too my brother pays me to clean the house and for washing his clothes. She's pathetic. I told her if I stole from you, you wouldn't have a damn penny left to spend. Tired of being accused of something I haven't done.
