Irony of the day

My two classrooms are at the far end of the THS campus, and I must go outside to move between here and the main building. Most days I make the trip once to check the mailboxes, run errands, attend meetings, etc. When I stepped outside today, it was pouring - I'm talking monsoon. I had on my coat and but my pants were soaked after my short walk.

Still dripping, I found this in my main office mailbox, from my secret pal:
HA! Too late ;)
