some days have a talent for bringing you down. others are better at lifting you up. and it's not all to do with the weather.
it might be determined by the health of your cat. if he gets sick in the hall way or curls up on your lap.
if a show you like is cancelled or confirmed for another season. or you find out that little dog you like is in another episode.
maybe someone you like ignores you. maybe they don't. bets are they don't know how important they are to you, at least not on that day.
