Do you put a period at the end of the sentence when chatting with someone?

I'm pretty picky about punctuation at all times. A forgotten comma can change the meaning of a sentence. A skipped period......well that's a whole other issue.

Not always

Most of the time I do. Old habits die hard.

Depends on how angry I am with them.

🤔 Oh, you mean when texting? Usually. My phone even automatically appends a period to a sentence consisting solely of emoji.

Since I am usually on my phone, it does so automatically, so yes.

By default, yep. But not always. It depends.

usually.

Sometimes.

sometimes.

Yes I do.

Usually, yes. Here it may run past bedtime and someone falls asleep.
