Yes and, as per Mother Thread today, God forbid one should laugh at anything another does not deem acceptable ()I sometimes press the wrong reaction like a when I mean or a when I mean and then think, tit!
To go back slightly - I already mentioned how happy I was to see so many introverts on this thread, and while part of me feels bad for being in what is probably the (nice!) mean girl motherthread supergroup we've got going on over here (I play the tambourine at the back and occasionally sing the dominant seventh of a backing vocal) I'm also super pathetically pleased to be part of it.
Don't get me wrong, I have IRL friends, but sometimes you just can't say all the things you want to ("your baby is boring"; "I hate your sofa"; "your partner is bleeping useless") and it's so nice having supportive candour.
ETA: @Badlyplatedflapjacks legend! Well done. Smegs all around (on you) x
