Ung. I don't have to say what not to do, I DID what not to do.
My great grandmas wake we had a moment of silence, I was a teen and I looked around the room (this was at her house, no body etc) and I spotted this picture pinned on her corkboard with some other stuff:
I slapped my hand over my mouth and instantly teared up it was the funniest thing on the worst moment of the worst day. Then I did the most logical thing TO do in this situation
...I tugged on my friends sleeve and pointed, he did the exact thing I did.
Needlessly to say, we got caught by my uncle and just pointed out. As soon as we got outside we started cracking up. As inappropriate as it was I feel like my great grandma would have understood and laughed anyway. My uncle understood just after a bit of talking, said he understood but didn't want us to suddenly start burst out laughing at that moment.
