Lol is something means to laugh inside your mind, if I keep
laughing loud here, people think i mad. And for those working in
office, if they keep laughing loud, good luck to them. They may end
up crying all the way out of the company. So lol is not mend to be
physical laughing, it is internal lauging which only few can master
it, and one of them is me and maybe the madam above
