Shoulder touch for flirting?

Anonymous
Is it flirting or just friendly? Which is more likely because I know it could be either way. Like if a girl that has shown signs of liking me just started touching your shoulder, should I read that as a way of breaking the touch barrier or just being friendly?

She has done it like once a day where she will pat me shoulder like 4 times with her whole hand. But I have seen her do it like one time to one of her friends...but that was only once and she is doing it like once a day to me. Thoughts?
