person A: I like to swim laps_comma_ and I discovered that you can see directly up my shorts if swimming behind me. 
person B: Wow. Must be a sight for those behind you all this time.
person A: Yeah_comma_ my girlfriend told me about it. I had been swimming in these shorts for weeks before I found out. I feel pretty awkward about going back now.
person B: It's ok. I'm sure everyone has their embarassing moments.
