At a recent baseball game Hallie and I headed to the bathroom together. While I was washing my hands Hallie stepped up next to the sink, unknowingly placing herself directly below - and within sensor-reaching distance from - the automatic soap dispenser. I immediately recognized what was about to happen but couldn't move fast enough to stop it, and after what happened happened, I made Hallie stand there while I fished my phone out of my pocket so that I could take a picture.
She wasn't upset when the soap dispensed directly onto her head, face, and dress. In fact, after she realized how funny I (and everyone else I sent the picture to) thought the incident was, she reveled in her soapiness for a while.
