At least once a year, my wife hosts a pink pool party - women only, no men or cameras allowed. So she started planning. Then she thought she'd also invite our sister-in-law and her many (I think 8, maybe more) sisters to come swimming some other time since my brother-in-law's pool is still empty. But that's another topic. Anyway, when my wife broached the subject, sister-in-law wasn't sure...one of her sisters is fighting some sort of cancer and is on mild chemotherapy and her immune system is pretty weak.
Sister-in-law: Christine has to be careful about where she goes so she doesn't catch something
Brother-in-law: His pool is clean!
Gee, do ya think?
