“By ignorance we mistake, and by mistakes we learn”

And boy did I make mistake today. I have finals for my advance swimming class today, but for some not-so-intelligent reason, I worked out my shoulders today. I'm starting to regret that decision.

We have to demonstrate the butterfly stroke and the backstroke today!! I have no clue how to do either of those haha (I'm not really laughing, I'm actually nervous), youtube!! help me!! I don't want to drown!
