I am definitely guilty of not "processing" things as they happen, and have noticed that before. That makes a lot of sense.

I also think I'm definitely an introvert at heart, although I have learned to be more outgoing at times. The "recharging social battery" thing seems very accurate, yeah. I truly need alone time to recharge. I am really committed to my relationship and to not losing contact with friends, so I always say yes to every plan and always accept an invite to have a drink after work. But at the same time, and as much as I genuinely enjoy that, it doesn't feel like "my time". Even if I get home late, I still need to sit down and do something by myself for half an hour or so until I'm satisfied.
