People who hover directly behind you in the supermarket queue, trying to pressure you to hurry up. This persisted through lockdown;
People who sit on the aisle seat on the train blocking the empty window seat, then 'zone out' with eyes closed/headphones on oblivious to anyone who might need the seat as the train fills up;
People who, when you are talking to them at social events, look over your shoulder and scan the room for somebody more interesting to talk to;
When two people in a group of three talk to each other at length about something they have in common which the third person doesn't, so the third person is unable to join in and feels like a gooseberry;
Even worse - when two people in a group of three WHISPER and giggle, and the third person is the only other person within earshot;
Worst of all: when complete strangers come up to me when out and about with my DS in his wheelchair and ask me personal questions about his issues. 'What happened to him? Was he born like that? How long has he been like that? What are his disabilities?'.
I usually respond to the last that he has 'wonderful boy syndrome' but they usually persist and then I stop communicating with them. They get nothing out of me.
