Potential partner

Hi my name is Peter. Two weeks ago I was doing a days work on a farm, the family that live there have three daughters anyway while having lunch I noticed the eldest daughter whose name is Kirralee, staring at me and occasionally smiling even throughout the afternoon she was staring at me. I'm 47 she is 26. Could it be that she is attracted to me? I consider myself very average looking to not very good looking, I have always been shit at picking up on signals from females. Why is she staring at me? I am also considering asking her out on a date. What is the best approach to take? Should I ring her or drive out to the farm and see her? she also lives with her parents. I am also shy and nervous I don't actually know if I have the nerve.
