Everyone thought it was strange but I took my underwear off when I was riding the bus.
Why would you take your underwear off on a public bus?
I was too hot with them on.
Having no underwear on is very freeing, but in public you might be looked at as odd. Just stop wearing it before you get there if you need to, instead of removing it on the bus. People will feel so uncomfortable seeing you undress.
I was careful about taking them off and the people that saw me do it didn't seem to mind.
I'm sure you were careful, but it still might make others uncomfortable and they didn't say anything to you. You're in a public area and need to be careful not to expose yourself or do anything unsanitary.
