The parent of my comment was making a joke (I doubt he seriously thinks people say "floating full stops" in the UK) so I made a joke too, in the same vein. You know, period/full stop...
It may not have been the best joke ever but I don't think it deserved 3 downvotes. People can be really tiresome sometimes.
(I'm not saying to you BTW; I don't think you downvoted.)
Edit: Okay, I received two upvotes after writing this, so now my post feels way too bitter. I'll leave it because I do think the point still stands - people are sometimes way too ready to downvote posts here (I don't mean mine, but anyone's) - but I'll also say people here are really very nice most of the time too.
