If a guy keeps pouring you a drink?

So we were at a round table with around 10 people for a party. I was the youngest (21) and this guy kept pouring me a drink (or making an excuse for me to drink) . Is this a good thing or a bad thing? I don't think he was interested in me, but is it conventional to keep pouring a drink just to keep the party going (since I was the youngest) for fun? Thoughts?
