not "all caps" just when you use a capital letter at the beginning of a sentence. it's like being formal but being formal in a no formal conversation is weird. so don't :)
friend 1: "Hey want to go out tonight? I found a nice place. What you think?"
friend 2: "ig it looks nice but why are you talking with capital letters..? it's to formal and weird, go look it up"
This little saying is used by Capital Letter Lovers, probably just like yourself!! Have fun with it; and remember to “Live, Laugh, Capital letter” my uppercase lovers
