I always try to play a set of tennis once a week against my friend at my local tennis club. Won our first match 6-3 3-6 6-4.
And then a couple of days ago I led 5-0 in the 1st set before he came back and won 7 consecutive games to win the set 7-5. I relaxed too much and lost my intensity after I was realised I was up 5-0. Kind of went a bit easy on him when he won his first game
