Often, I think people are just trying to make conversation asking things like are they walking yet, yk? It's just small talk even though it's hard not to take it personally or worry.
This^^^ It's kind of like the 'how is he sleeping question' when they're infants. So silly, really, because each and every one is so different, but it's just what people ask to make small talk. It is hard though, to let it roll off your back sometimes. But, all the replies here should reassure you, he's developing perfectly normal! My three were 13, 16, and 12mo respectively.
I do have to say though, that hearing the 'walker or talker' thing wasn't really helpful for me, unfortunately. My G was late in both, not doing either til 16-18mo and he didn't say much until he was two. But, at 3.5 you'd never know and a lot of people compliment him on his clarity and vocabulary when speaking. He just took his time. I wasn't too worried, although I did have moments of uncertainty, because he had good gross motor skills and a good understanding of communication (he used sign language and I could tell he understood everything I was saying). So, I knew he was working on those skills and they would come in time. Just as F is doing now.
