Question of the Day!

I know this is going to be a strange question and again, not sure if it's been asked but here we gooooooooo.

Do you have a personal favorite punctuation mark you like using or find extremely useful? Can be more than one.

My favorite one I found out when I was writing is the "semi-colon." Lot of times I don't want to use the comma because I've already have. The semi-colon allows me that pause. Not sure if I explained it correctly enough but hoping you all understood...lol
