I think "rules" and etiquette have changed over the last few years. People don't "dress up" to go to viewings like they used. I probably would have been giggling with you guys 'cause that is funny!!
We had some staff "turn us (upper management) in" to the Union at a funeral for one of the individuals that we took care of. We were sharing our favorite "Frank" stories and they thought we were inappropriate because....*gasp* we were laughing at a funeral home!
Now you have to understand that "Frank" was Bipolar and swung from the extreme opposites in moods. One day he would be down - he'd stare at you until you tried to make eye contact with him and he'd look up at the ceiling/sky to avoid eye contact and then go back to staring you down.
When he was up, he would box and spar with things on the wall - pictures, Christmas wreaths, etc. It was so damn funny!
