As you short guys know there are problems sitting down in a kilt and never mind the pleats as they are a miner aggravation that is easily overcome. Men come in many different heights from very short to very tall. Regardless of height or weight a mans “stuff” (you know those things that so shock the world if they are seen) are all approximately the same size. There are exceptions as can be seen by watching porn but by and large all men are about the same.
Not so with waist to knee cap distance. A man that has a 24 inch drop has a 5 inch advantage over a man with a 19 inch drop(me). The kilt gets shorter in back as he sits down and if he has any butt at all it gets way shorter. For a man of my girth (42 inches) and a butt it gets shorter than your “stuff”. Hot vinyl car seats can be painful. Don't sit on a glass coffee table while someone is under it. You'll scare them. Concrete bleachers are out especially in winter. Anything with splinters is out. Don't even consider outdoor furniture with an open weave especially the plastic kind that not only gets hot but loose things can get caught in. You could end up with a chair hanging out of your kilt. Don't sit on a log with rough bark. Your really don't want to sit on anyone's lap unless you know them well or want too. For those with long belly button to knee cap length this is not a problem. They have other problems to be sure but it usually involves their head.

Even at my age I am still aware of my “stuff” at all times so I would really rather stand thank you.

Believe it or not riding a bicycle is OK and is actually more comfortable than shorts.
