Well, I couldn't help thinking how I'd feel if that had been my stroller. I have little ones who weren't on this particular trip with DW and I (second honeymoon), and I know I'd have been disappointed with myself for not thinking that it might rain and leaving the stroller uncovered. I'd be scrambling for a way to have DS in stroller without having the associated wet bottom because dad wasn't thinking/planning. Felt like I would have appreciated someone doing a nice thing for us, and wouldn't hesitate to do it again. Might there be repercussions? Sure, but I'm willing to face those because there was no malice in my actions. I won't live my life afraid that doing something nice or right or good might offend someone. If they're offended by kindness, they're vacationing in the wrong place!
