My aunt can be immature

I traveled with my aunt to Mexico and on return flight her jar of peanut butter had to be thrown out since it was too many ounces. Now I didn't know it was in her carry on also it's a peanut butter not sold here so she pretty disappointed.

Anyway I forgot about it since I didn't think it was that big a deal, it's just peanut butter. Day later after we're back home she's talking with my mom & starts telling her it was all my fault her peanut butter got thrown out since I packed her bag and that I most likely wanted to be only one with a jar, then quickly hung up she was mad at me and didn't want to talk or even see my mom.

I told my mom my aunt was being dramatic & lying her ass off because the person who helped pack her bags was her brother (my uncle) I didn't even touch her bags and if anyone was to blame it was him. Also what makes her immature isn't that she lied it's fact she's this upset over damn peanut butter & avoiding my mom.

I told my mom if she's that upset I'd just find some online, luckily I found a jar at a decent price online, honestly I wanna give her a petty comment when I give it to her just to make a point she's being childish lol
