My sister (32) is pretty immature, but this part of her behaviour I find unacceptable.
She has always found it side-splittingly hilarious when anyone does something painful like stub their toe, bang their head etc. During my teenage years this wound me up no end - imagine being in the throes of agony and someone laughing their arse off at you.
So basically, she has started doing this to my toddler daughter. DD whacked her head on a table to and as I was comforting my wailing child I could see my sister across the table, also crying, but with uncontrollable laughter.
I think it's partly nerves, and the tension of suppressing laughter makes it stronger. She loves DD. It makes me want to slap her, though. I also don't want DD to notice because I think it's very disrespectful. She's too young at present to notice.
I've learnt not to confront my sister because she goes totally apeshit if you question any of her behaviour and we were in the middle of nowhere with only one car so awkward drive back, but I suppose I'm asking WWYD in this situation? Is it a psychological thing? Thanks for reading.
