If you notice that you're particularly tired after being around a lot of people, or something that grates on any sensory hypersensitivities, then I would say it's quite likely. I find that it can also be caused by the extra load on my brains when I interact with people - for example, trying to work out the context of a situation by working through all the possibilities, to compensate for missed social cues. If I go to a social event where there are a lot of people, I'm usually completely exhausted the next day, and have to spend some time away from people to recharge.
