I can sometimes be quite tunnel vision-ed, and I can't really discuss this with RL friends so I'm after opinions.
My youngest DD is disabled. Five years ago she had a horrible fall in a supermarket disabled loo. Her condition was deteriorating, but we didn't quite know what we were dealing with yet. I popped her on the loo as normal and as I turned to get wipes she had a seizure and fell forward. She cracked her head on the floor, lots of blood, and broke her arm. The seizure went on to be the longest she'd ever had at that point.
My 7yo DS was standing outside waiting so I opened the door and sent him to customer service to alert them to the fact I was calling an ambulance (due to the seizure going on and on). A lovely member of staff came with a first aid box and blanket and we were focussed on DD.
While we were waiting a woman came along with her DS and asked if we were going to be long. She wanted to use the loo as her DS needed, he didn't like going into the ladies with her as he was too old, but she didn't want him in the gents. He was 7/8 looking. The staff told her we were waiting on an ambulance and she went away.
In the twenty minutes or so we waited on the ambulance she came back three times. Her DS clearly bursting more and more. The last time she came she actually tutted and said "Oh, you're still hogging the toilet". My DD was in the midst of another seizure so I snapped and said "Either take him into the ladies or let him into the gents ffs. We're waiting on an ambulance and we'll be here until they get here." She called me rude, the staff member asked her to walk away and tbh I never really thought anymore about her until recently. She made a scary event so much more stressful.
I take my DS to an event once a month, it's our time together away from the stresses of him living with his sister. It's purely our thing. He's been quite friendly with another boy there, who came with his Dad, but it's never been suggested that they meet up away from the event. At the weekend the boy came with his Mum. It's the woman from the supermarket.
She suggested that the boys could get together at other times since they get on well and that maybe we could have coffee - she clearly doesn't have any recognition of me (which is understandable). DS is absolutely non-plussed by the suggestion. At his age he does a lot of his organising on his own with his friends. I have absolutely zero inclination to have anything more to do with this woman - at best she was having a bad day and behaved like a dick. At worst she has zero empathy.
AIBU to discourage any suggestion of this friendship pf DS's being anything more than it is purely because of the woman?
