How do they wear long pants? I tried it myself -- if you want the pants to not touch the floor while you are wearing them, you have to
Sit down and fold the pants' sleeves in half, fixing them in place with hands
Put each of your feet and kick outward so that the folded half extends with your legs going in them
repeat for the other foot
Obviously for shorts this method is unnecessary and you can balance your way to wearing them :)
Does everybody do this? I think I found this out looking at my roommate do it but I can't remember how I got to wear pants this way. Am I really the ocd/pernicious sort? I'm guessing if you are acutely aware of how dirty the floors are if you step on them with shoes worn outside
one really doesn't want his/her pants to touch the floor very often, if at all.
