Q: but hold on... why is lower case the normal case? didn't UPPER CASE come first (with, probably latin etc) and when did lower case become dominant? not sure why i'm asking you instead of researching it myself
A: i don't know why lowercase is the normal case, but the reason why i say it's the normal case is because it seems to be the one everyone uses, normally. think about it, you don't see people going "HI JEFF, THANKS FOR LUNCH YESTERDAY. LET'S TOUCH BASE LATER ON IN THE WEEK"
