Is my mom Switching to hot to cold on purpose

I needed a Wipe to Clean off my hand in the Car i Asked my Brother for a Wipe and she got upset because I asked him for a Wipe instead of her - she asked why are you asking him for wipes and not me - she said that I’m hurting her feelings and that I’m holding a Grudge against her she said when is the expiration date on my Grudge - Personally she’s Tearing up to see if I care about her and I’m not falling for that shit
