Ugh I hate trying to make mom friends, the Audacity

I’m newly single mom and my son play baseball and it was time for the end of the year party so the couch asked me to plan it no problem right???? he told me ask everyone to donation and give the donations to me still no issues right !! Wrong this other mom started telling the other moms I was planning it instead of donationing my self since I was a broke single mom and it wasn’t fair I could literally Hear her saying that ... so I confronted her I asked her why she assumed that. She said I drive a crappy car and have a small house . she said she knows I get no child support. I look her in the eyes and told her I didn’t owe her an explanation since I actually donated move then everyone to cover the rest of the party. the little 20$ she gave wasn’t enough, and I paid 150$ so the kids can do something fun. She got all pissy and started to get loud with me then I must get all my money from welfare since I don’t have a job, so she actually paid for it since she pays her taxes. At that point I was done..... I saw red but I stayed calm. And said again I don’t owe u an explanation of how or why of anything of my life and tried to walk away she grab me to turn me around and I was still calm she said I was just jealous of her , her life and her kid since he’s good at baseball.!I couldn’t control my laughter. At this point everyone was look at us and an other min tried to tell her to stop she was being ridiculous( cause she knows me)She said no I owe her an explanation since she a tax payer and I’m on welfare. I told her I’m not on welfare, I drive that car cause I like it I have a small house because it’s near my parents and I might not have a “job” cause I personally own the apartment complex she lives in..... her face was priceless. Then said I was a lier that ” Bob” owned it and took care if everything ummm bob works for me. Her face dropped she was still and quiet. Then I handed her the card with all the information for the party and said don’t forget to RSVP and walked away.

What is wrong with some ppl seriously didn’t ur mom teach u not to be an asshole
