My coworker guy friend and i were waiting for our friends in a park today. I told him to take a seat on the bench across from the bench i was sitting on. Few minutes later , he suddenly got up and came and sat right beside me on my bench , saying it feels weired sitting away from me. His was totally leaning into me with his shoulders, arms and legs touching mine. I was shocked because normally he is a very shy guy and we are just frinds and i am not touchy feely with him. Why did he DO that ? Is he interested in me ?
