cursed injuries!!!

Why do surf injuries always happen on really small days????
Just this afternoon I had my right cheek (think face, not other) split by the tip of a shortboard after its rider lost control and fell off, shooting the board right into my face... Now I have a (nicely) swollen right cheek with a little slice out of it (not enough to need stitches).
This is the first painful injury i've got in the surf, and it happened on a day when the waves were almost too small to ride... so disappointing.
Has anyone else noticed how most injuries happen on small days? (Except obviously for the really big days which just cause havoc).
