All my sims are obsessed with grilling. When I switch to the next house during the night (3 AM normally, because I want to get the 5 AM growth in their garden), if they own a BBQ there is a 99% chance...
I find the same with pools, in my sims old house I had a "pond" made from a pool and every single time I loaded in game one of my sims jumped into the pool and ended up in their swimming costume for ages. ?♀️
