quite a blunder

so after a few days of treating a zit that was growing underneath the skin (those annoying zits), on my forehead, but nothing visually showing up, i realized that the zit pain i was feeling was really a bruise from when i hit my forehead with my tennis racquet, when i was doing a one handed forehand (whipped up for top spin ).

at the time of the hit, i felt more stupid and didn't think anything of it.

my frame is made out of metal. i'm just lucky i didn't knock myself out cold.
