I was just talking with the receptionist where I work and she said that she deliberately chooses not to learn because she's afraid of drowning.
These days I really do make a conscious effort to avoid making people feel stupid. Honestly. Having more friends is all part of my devious and sinister master-plan to conquer the universe.
So I stood there for a good solid 3 seconds waging war inside my mind about whether or not I should inform her that if she doesn't learn how to swim, her chances of drowning will dramatically increase.
In the end I gave into temptation, justified on the basis that other people make me feel dumb on at least a tri-daily basis, so it's fair.
Here's a picture I took of my feet.
