I just made one of my male coworkers SO uncomfortable. He was looking for me and saw me coming out of the empty office on our floor. He was all, “Hey, about blah blah blah”. He then saw the bottle of milk in my hand, and LITERALLY turned around and was all , “oh, sorry, oh, eeesh, sorry”. I was totally cool about it. "Don't worry about it," I said, and politely put the bottle out of sight (mainly so he'd stop twitching). He just kept saying, "Oh, sorry, really, eesh, sorry." "Seriously," I said, "Don't worry about it."
But seriously, so done with this.
