so I'm going to just write it down so I can (hopefully) forget about it.
There has been a terrible, sad incident in Ireland where 9 yr old twin boys were stabbed to death in a suspected murder/suicide by their adult brother who was found dead a short distance from the house.
There were a group of school gate mums from DS's class outside the school discussing it and one said "I can't understand how someone could do that to their own brother" and someone else said "No, apparently the older one was adopted" and at least half the group did that multi-tonal "oooohhh" thing as though that explained everything. One of them, who knows that we adopted our DC, did pitch in with a belated "not that that makes any difference", and there was a bit of an awkward silence before someone else mentioned that they were a settled traveller family (again as though that explained everything) at which point I distracted myself by fiddling with my phone.
GRRR
That's all.
