Yeah, it's a tricky one sometimes, in terms of letting the other person know your basic intention when gifting them with something. So I think in the example you gave, everything was cool. And then, maybe he just felt like he'd give you a call realising the type of good neighbour you are, and to get to know you a little bit as a person. If I were him, I might want to do that. But at the end of the day, it all sounded very casual without any major things going on. No expectation.

(Watch out he doesn't ask you to babysit next. Taking advantage of kindness hah)
