You were very brave and your subconscious brain knew exactly what to say and do to keep you and your baby safe.
Well done.
Not ‘I should have stood up to him’! But a heartfelt well done, because you appeased him and calmed him as best you could in the moment, you managed to keep a very scary situation from escalating.
No thanks to that lump behind the counter who sounds utterly rubbish (ok, that’s me being cross and a little unfair, but grrr that she didn’t rush to your aid as soon as the danger had passed, but many people are utterly shite in emergencies!).
Anyway, back to you. In the face of shocking and unreasonable aggression from a man who was physically stronger, and not bound by the limits of normal rules of society, then you did what you’ve learnt to do. Which is not to fight back. You had your baby to take care of and you knew you had to make sure you both came out of this freak encounter ok. You did well. Bravo. X.
Now... who knows what this man was pumped up on. Adrenalin, fury, steroids, testosterone... more, or less of these. Or just anger coming off another argument or bad situation that he cannot deal with, so jumped in his car and drove like crazy, then you come along for him to fix his anger on.
I suspect you are nothing to him. In the nicest possible way (!). You were just another thing to fix his anger onto, a cardboard cut out to vent on. This whole incident was about him, not about you, I bet his ego doesn’t have much room for anyone else but himself.
And that’s reassuring for you I think? Because it means he probably won’t remember much about you. So, unless you have some very recognizable things about you and the buggy, I don’t think he’d even be able to think what you look like.
If it makes you feel better, put that jacket/ hoodie in the washing pile for a week or two, if it’s very recognizable. Although I don’t think that’s actually necessary, but it might make you feel better. And if you’re still worried, you could wear your hair a little bit differently? But only if this is going to help you feel reassured going outside again. If thinking like this makes you feel more anxious then please stop and don’t follow any of these suggestions at all!
