Why insult your guests when they want to know what time it is? Just nonchalantly show them a quarter of the clock face and they can certainly figure out the rest. Some clocks have no numerals at all, so at least this $30 12-to-3 Wall Clock is a start.
Besides, if you’re one who likes to wait ‘til the midnight hour, all the good stuff happens in these three hours, anyway. Unless you’re talking about PM, which is about when you might be waking up after such early-morning escapades.
