How do you cope with the embarrassment of their behaviour and actions?

For the last few years if I’ve been out in public, I’ve been absolutely dreading bumping into ex friends, neighbours, acquaintances etc of my mum. For the sole fact I feel like I’d end up apologising to them profusely for my mum’s behaviour towards them.

There’s a girl I went to school with who mum reported to the police because she parked her car outside mum’s house a couple of years ago as the street was packed and she couldn’t get outside her own house. Or the neighbours who’ve accidentally let slip of their door, it’s slammed and mum’s reported them to the local council because they’re too noisy.

But last night, I was having a quiet evening just scrolling Facebook, when I saw my mum’s name crop up on a local Facebook group, raging about a young girl personally working in a charity shop and not being able to sell to mum what she wanted.

Just as I think she couldn’t stoop any lower with her actions, attitude and behaviour she berates a poor young girl working in a charity shop for just doing her job, all over a local Facebook group. I’m so embarrassed it’s unreal. Embarrassed for her, embarrassed for myself for people who know me and know that’s my mum.

How to actually deal with the embarrassment?
