I remember during Covid lock downs extroverts were loosing their minds and blaming their extrovertism for their cabin fever.

First of all, true isolation is unhealthy and crazy inducing for everyone, that's why they still use solitary confinement in prisons for further punishment, so no, extroverts, you're not special for feeling depressed during a global pandemic. (but yes, it did suck extra for them)

But so many extroverts seemed to assume lock downs were an introverts wet dream. There was very little attempt to understand each other. I'd see introverts empathising with extroverts who were struggling, but the reverse rarely happened, extroverts just seemed to assume "you introverts must be loving this solitude" and when myself and others tried to open up about how we were struggling I would hear "yeah but you like being alone, you're used to it" like that makes it easier.

At no point did I really see any of the extroverts I know, or anyone online posting about how "wow, being pushed this far out of my comfort zone by lockdowns sucks, is this how introverts feel when I force them to actively engage in crowded, highly social parties?"

Not that I expect the middle of a planet wide plague to be the time I'd suddenly expect people to show self reflection and emotional maturity, but it was still worth the observation.

I don't. I generally dislike eating out or going to movies or events alone. I'm also generally very introverted but I happen to dislike going out and doing stuff by myself.

One big part is that I can chat if I eat with someone but if I eat by myself I'm understimulated. And if I already sit there and look at my smartphone while eating I can as well just pick up something from the bakery around the corner and eat it while looking at my computer screen.
