Bill is a yapper. A big one of that.

He can sit there for HOURS, talking about what he likes, what coll or funny things he's seen during the day, how his shows went, ECT.

Unlucky you... You're the only person who will sit there and listen, rarely complaining. He will talk your ear off if you let him, even if you're busy.

That's why he likes you so much, you just listen, occasionally giving feedback. He likes that. You're sweet to him.
