I would say ‘heh : )’, but that would seem a trifle thoughtless/heartless.

Really though, it was so I could get in the punchline about the kids: I saw an advert for the below firework … ooh, a couple of decades ago almost … that had the tagline “Give Your Kids A Golden Shower” … and the post was really a poor taste allusion to that.

But I thought I might as well make the post educational at the same time ; )
