So...yeah...
I was talking to him in chat. He paid me for 2 bonds then went afk? He then came back and asked in the public chat if anyone is selling bonds.. I said I was and then I was like, 'oh, hey! You already paid me for bonds'. He then remembered and said, '2 bonds?' I said 'yes', then he said 'ok'.
He went mia again...
PS: MIA = missing in action.
