I know what you mean! Years back I was in a pub with a friend and remarked I liked the jumper a very stylish girl at the bar was wearing. Friend came straight back that I couldn't say that, because I couldn't see the front, and it could have Mr Blobby embroidered on it for all I knew.
Such a random and stupid thing to say but we both laughed until we cried at the thought of it, and took about half an hour to recover.
(I appreciate that you probably had to be there).
I often make my DH, and myself, laugh by messing with Alexa when we're in different rooms. Dropping into the room he's in with stupid sound bites, or faffing with the lights.
I couldn't bear to take all of life seriously, there's enough seriousness we have to deal with, without adding more voluntarily.
