I have an acquaintance/friend who it turns out, has been lying about their background. This wouldn’t matter but for the fact this friend consistently looks down their nose at others, even me, for coming from a regular background.
Friend had told me they grew up in rural Sussex “a the family home” and attended a local private day school because her father couldn’t stand him boarding (like he had done).
I found out, through a chance encounter with someone who went to her school, that actually she grew up in outer London/Essex - near Woodford. She also went to the bog standard local comprehensive school. Her parents only moved to Sussex when she went to uni, and live in a new build bungalow (so not “family home” in the sense they wanted me to see).
AIBU to tell friend I met their old school mate and we realised we both knew you?
