What would you do if you were the opposite sex for one day?

If, one morning, I woke up and realized I was no longer female, but instead a male, my day would most likely not be the same. Being a male would mean no reason to put on make-up, straighten my hair, etc. I would take a shower and not have to worry about conditioning my hair after I washed it because shampoo would be enough. My shower would probably go from lasting 20 minutes to a total of 5 minutes. After that, I would probably eat massive amounts of food because it wouldn't matter how many calories I ingested for only one day. I would have to learn how to go to the bathroom as a boy too. Going out and seeing how people would treat me differently would be interesting as well: no more doors automatically being opened for me by other boys, etc. Many aspects of life in which I'm used to would change.
