Thinking about this... Pat has always been a challenge to keep clean. His mother used to complain that we "never let the kids shower", but they'd come to us smelling... Well, horrible. The first thing Belle would do was hop in our shower. Pat, on the other hand, never really got into it. When he was small, we'd bathe him (mostly Bill due to biomom's accusations) - I could do hair when he was in a bubble bath. He did like to sit in the bath and play, though. We did every other day, then pushed to every day when he started doing football. Even so, he'd be in for 2 minutes and then back out, without doing hair, etc. Cold water. Belle started harping on him. Well, apparently his sense of smell is completely gone, as he told us and we also noticed.
But thinking about it, his might stem back to biomom. See, when I met Bill, Pat lived with biomom, Belle, and biogma in a small trailer. I would be willing to bet good money he didn't get much in the way of real bathing, in hot water... Especially as Belle got a little older. Bill did mention that biomom loved LONG HOT showers. Since she worked a lot of 3rd shift... He probably got his bath after her and Belle's showers. If he didn't, she probably had no time in the morning. So he constantly smelled like urine until about 3rd grade when we took over residential.
And, poor kid also inherited biomom's strong body odor... But when you add up all the shower issues as a young'un, that might say something.
