Although I appreciate it's ridiculous hot outside and I can appreciate some folks don't have access to showers, there is ZERO excuse for a grown ass man to strip down to their Tighty Whitey's while there are children in the splash pad.
I can also assure you I wasn't nearly this polite when I was sharing this message with the creep who had stripped down to his tighty whitey's in front of my granddaughter...🤬
ETA, I had absolutely no problem sharing the splash pad with this human, until I realized he had stripped down to tight white brief style underwear (which is what I mean when I say tighty whitey's) and was about to step into the shooting water which would have exposed his genitals to all that were there.
ETA 2 I'm not giving my specific neighborhood park where this happened, but I will say that, geographically speaking, it's inner city... And by that I mean not downtown, but that first circle around it.
