Am I being used? I'm not so good at keeping friends. I seem to attract people to me naturally when I make an effort not to speak to anyone.
This one person I met asked me if I wanted to smoke with him and I did but now he asks me for rides occationally. Though he always gives me gas money. He also asked me to pick breakfast up from a fast food place on the way to work and he paid me for it.
He also wants to work out with me at the gym.

Are these natural things that people do or am I being naive in thinking that the person is a friend?

I should mention that I don't have a single friend and haven't had any real friends for close to 7 years so I don't know how friendships work.
