The grocery store knife debacle

At woodmans with my mother…I can’t recall why this was a thing or idea or issue..must maybe be related to gun violence or something? But, she had said something along the lines of I can’t remember but we split up and had to hurry and check out and I was under the impression I should or was supposed to or had to take out the white steak knife I had in my purse and turn it like outward like with an upside down fist and just hold it there as like a let me through don’t fuck with me thing. A couple people saw and moved out of the way of my half empty cart right away as I went to meet my mom at checkout. But it was all of a sudden when we were leaving they found out and were like after us. Or me. Because even though it was her idea and instruction only I did it so they were only after me. I left with maybe a different friend or in their car?…stopped at a nearby sort of park and stuck it into like the trunk base of a tree under some moss until it was nearly under the surface but just the tip enough I could go back and get it. Kinda was panicky about that but there was no time. Stopped at some older couples house? Wait it was also my friends…Rebecca knight maybe? Can’t remember but we were in her room. The cops came over. I was afraid to get in trouble. I borrowed some sort of outfit and boots. Don’t recall the rest right now but it was very strange.
