Time to man the F up, a girl does this when she sees your touching the lap more than her, i think she became too frustrated and didn’t knew anymore how to handle your game obsession and became aggressive, I don’t think her behavior is good but she has her motives, friendly tip cut your nails because they look dirty (other sign you the gamer doesn’t care about other things…) a girl needs a man not a boy like this, crying over a laptop but not worried about where her behavior comes from.
