Welcome to the forum Nafowler. And to BPs!

Many times there is no reason at all for a certain position. Sometimes it may be to feel secure. Or they may be trying to warmup or cool down a certain part of their body.

Now let me ask you a question. Why do you sometimes lean with your back against the wall with one foot on the ground and one foot against the wall?

I'll tell you, Because It's Comfortable!!
