Merlin 4.06 - Arthur and Guinevere - Too Perfect

If you were sitting on the bus or train going to work or college or wherever and Bradley came and sat right next to you, on the next seat, thigh touching yours, what would you do? The bus/train wasn't full but he chose to sit next to you. You were reading a book or had your headphones plugged into your ears and didn't take any notice at first, then when you looked up... there he was!

Oh, and he said hello, with his lovely smile and blue eyes piercing into you.

Be honest, what would you ACTUALLY do or say. Would you even say or do anything at all?
