Bola kita, bola kita!

I played futsal for the first time yesterday. Today we had friendly match with people from Finance Office. Before the game started, I thought it will be nice to be friendly, so I shook hands with one of the player, introduced myself, asked her name and told her I didn't know lot of people as I just recently came back from my study leave. She smiled and we chat a little. After played for a while, I sat at the bench. 15 minutes before the times up (we rent the court), I went in again. I asked one of the player her name and told her mine with smile. Only few minutes later I realized she's the same person I asked before. No wonder she pulled a weird reaction. How socially awkward can I be?
