My mom gets onto me for going out alone

I am 22 and I sometimes go to the store, Walmart. It’s just down the road and sometimes I go at night. I live on my own with my so.

Well my mom called me while I was at Walmart and I told her that I was and she was like “ALL ALONE?” And i was like “... yes?”

“Why would he (my so) LET you go alone?”

I was like.. well mom he doesn’t tell me what I can and cannot do. He knows where I’m going and how long I should be gone and if I’m gone too long he’d get concerned and try to find me. But he’s not gonna tell me I can go to Walmart. Lmao

Is it bad to go to Walmart alone? I park close to the doors. It’s not like I’m out walking in the city alone.

I’m also a crazy bitch and if you try to snatch me you’ll lose your eyes. I’ve never had a bad experience, I come and go in peace.

I also have this issue where I go to Walmart with one important thing to get, get distracted and buy everything but that one damn thing I actually went for so I go back when I realize I suck at life. Which is usually at night.
