I agree wholeheartedly. The supreme arrogance of the, 'excuse me' brigade when I step to close to THEM.
The thing is, I have had people say "excuse me!" in quite and indigant way that pisses me off. However I always step back if I can and very often what appears to be someone being cross or arrogant is just people being genuinely anxious. It is very easy to misread social signals, even for the most sensitive of people.
I try to cut people slack whatever way it is. Someone walked into the back of me recently, not looking where he was going, and immediately started souting at me to mind where I was going.
I pointed out that he had in fact walked into me, at which point he started shouting that I was at fault because I was wearing a mask. Fortunately other people saw what had happened and were laughing at him, he really was being a total arse.
He was with his partner who had a baby in a pram and 2 toddlers. I just clocked them all and thought to myself that I have no idea about the challenges they are facing, with young kids they may be sleep deprived, he was behaving badly but could have been made redundant, facing homelessness I just don't know.
Also I have behaved in a less then angelic manner at some very highly stressed times in my life.
Similarly when people are anxious about intrusion on their space I find that being kind and apologising, even if it wasn't my fault, often beings a reciprocal apology and a moment of socially distanced bonding.
I don't live my life to make sure you're ok. I respect social distancing but other people just being precious and me me me are just that.
In a pandemic we all have to live our lives to make sure that we are all OK. It is the only way we will get thought this. I think you might want to consider cutting people some slack. They probably are just stressed and scared and don't mean to be rude.
