But you can laugh, out loud or otherwise, and your dad's probably got nothing to do with that, nor has that got anything to do with getting to a launch. In this curmudgeon's opinion, "LOL" should be reserved for use as a comment on what someone else has done, stated, or shown, though it could apply to one's own description of a situation as in your case. It should in any case be set off from other language by some sort of punctuation. And did you really laugh out loud at the notion that you need a ride to the launch?
