I encountered a man on the street who just came up to me out of no where. He ask me what time is it.
I thought he was stupid because I was not wearing a watch today. It only took me a little more minutes to realize that-
I had a phone and he doesn't.
Remember kids, don't assume that person is dumb.
Because maybe you're the dumb one who had a clock on his/her phone all along.
That's why phones are useful this days...
