I'm on my (30) Night Elf on the boat from Ratchet to Booty Bay. There is one Human Warlock about level 22 on the boat. There are three Horde people on the boat, one at level 1, one around 20+ and one level ??.
I see in chat the Human says "What level are you?"
Now, if he's talking to me then he's pretty high level to not realize he can see my level. If he's talking to the level ?? Horde then he's too high a level to not know that the Horde guy can't understand a word he says.
I just kept quiet and danced with the nice level ?? Horde Orc who danced with me. :P
