I haven't found myself jusy breaking down and crying yet but I find that I will laugh so hard I start crying which I then can't stop.
For example, last high DH was eating a box of nerds and spilled the box on the couch. I was laughing so hard watching him clean them up and then our dog came over and cautiously munched on one. I lost it and started sobbing/laughing and couldn't stop.
So weird?! Anyone else? Tell me I'm not alone...
Re: crying
It's hard to explain but I think I know what you're saying, OP.
