I pretend not to notice when someone does something embarrassing. I'm just going to act like it never happened.
Why did you pretend to not notice?
I wouldn't want them to know that I saw them do something embarrassing.
That's very nice of you. I can understand that no one wants to be seen doing something that would embarrass them.
Yeah same, I definitely don't want to know anyone saw me do something embarrassing.
Everyone does embarrassing things and you are being a nice person by letting others do things without putting them down.
