Mardson is very sensitive, especially when it comes to sounds. When he uses public restrooms, he will plug his ears when the toilet flushes.
The other day I noticed him preempting the toilet flush by walking into the stall, and immediately plugging his ears. He wasn’t doing this every time, and it took me a while to figure out what the trend was.
He has learned that when there’s the little black eye of the infrared toilet flushers, there’s no controlling when that thing will go off. So when he sees the scanner, he just plugs his ears and tells me “okay dad, take my pants off and place me on the toilet; I’m ready to go”.
