Could a older woman be into me? At times she would pay attention to what I was doing, laugh at my jokes. Could this mean that she likes me?

I was on a road trip and there was this older beautiful woman there. we barely talked and she is a quiet person so I get that. at the house we were staying at, at times she would ask if I needed any asistance what so ever. I would help her carry the luggage or anything she did. In the car our legs were touching and our elbows were touching. This one time the back of my hand was on the back if her hand and she didn't move at all , it seemed like she was comfortable with it. When I was leaving to back to my place she said bye than said my name with a big smile on her face. What could this mean?
