Neighbour has some health issues, we don't know what exactly but he is visibly increasingly slow taking their DC to school and recently started using a stick. We exchange a few words, so friendly but not friends. It's a fairly short walk to school, and would be just a few metres further to that gate than dropping our DC, so zero hassle for us to drop or collect. I think it would be nice to offer in case he is struggling too much, just casually as "if you want us to drop/collect any day just text" and not mentioning his walking issues. DH thinks the neighbour likes being out and maintaining the independence despite obvious pain, but more importantly thinks the neighbour might be offended if we offer. Thoughts?
