On the bus ride to somewhere where I didn't want to go, I noticed a flock of birds flying in the opposite direction, towards what I presume is the South, to the warmth.
Which reminds me of a lottery commercial I saw wherein a couple are on their porch wearing warm clothes and the husband keeps commenting on the birds flying south and in the final scene (after they've won the lottery) "look honey! the birds are flying in!".
And thus I christen the warm weather over, and with its departure arrives the sneezing, sore throat, mucus and tight lungs.
