Yep, in the last place I lived we had a really kind and friendly neighbor who is also a handyman of sorts and helps people on the block with whatever random small problems they have in their houses. He knows everyone and regularly introduces people to each other. I'd be standing on the sidewalk talking with him and someone else would walk by. He'd say "oh have you met Such-and-such?" and call the person over. He single-handedly makes that block like an order of magnitude more neighborly and sociable than it otherwise would be.
