WhatsApp group of multiple friends, discussing something to do with the step children of another friend and an annoyance in that regard.
Cue lots of talk of how rubbish it is having step children, having "random children" in your house etc. There was talking of how none of them would do X Y or Z for kids that weren't theirs, wouldn't pay for this or that etc..
Would it upset you if your partner was part of this group and didn't say anything to the contrary of the above although didn't outright say anything awful either?
