Dave, you know sometimes it's strategy to intentionally put yourself on two. But in that case you shouldn't need the other guy to remind you.
I agree - but a rule's a rule. Personally, I hate a lot of our rules because they make zero sense. This is one of them. If someone's on 2-- who cares if you tell them. If they don't know what time it is, tough noogies. But alas, I don't write the rules... there are other powers that be.
