Smile.....why smile? Smile is one of God's greatest gift to us. Smile can make you happy, and smile can make other people happy. It is not hard to smile. Just contract that facial muscles of yours and smile. It is depressing to not see a smile. I know, I also sometimes doesn't smile when I'm in a bad mood. But each day, I'll try to smile so that people are happy with me. Living with someone who rarely smile to you every time you bump him/her always depressing, at least to me. Everything changes. The only time you communicate is when to ask for rent, bill, or asking some favors. Strictly business. No more social interaction. Maybe it is our fault not to initiate such communication, but at least if they smile to you every time you bump each other, it is far more than enough to make people happy and feel great!
Hence, please smile to each other, especially to your room mates or house mates. Smiling can brings out happiness and great feeling within us. Even Prophet Muhammad (pbuh) also encourage his followers to smile among each other. So, let us start smiling......NOW!!!
