Sometimes that's me.

Hey if you need time to yourself to rest or recharge, there's nothing wrong with that. Just try to not get too burnt out and relax when ya can!

Understandable.

It's perfectly acceptable to need alone time to yourself for as long as you require!

Man, after a music festival, a work trip overseas, burning man, and a furry convention all in two and a half months span, my social battery was so completely drained that I'm only just now managing to get some charge back in to it.

Communication is so very important in this day and age, even at times when you don't feel like chatting. Most people, especially friends will understand if you need some alone time so long as you tell them that. Ghosting them and not responding can lead to them thinking they have done something to anger you and only try harder and more frequently to get in touch with you to find out if they upset you in any way. Just a hello and quick synopsis of not feeling talkative can prevent a whole lot of drama and worry. I'm not saying respond immediately or anything, we all live busy lives and can't reply all the time. I'm referring more to days passing by without any sort of feedback. Nobody likes being ignored for no reason, please let them know that!
