I was told it was weird that I'm nearly 50 and have zero kids. How is that weird? Wouldn't that be a bonus or a positive

A lady I was talking to said it was weird. Personally wouldn't that be a bonus in dating someone? No ex to deal with or kids that might give you a hard time. Kids are just something that never came to be in my life. I don't hate kids but it just never happened and in a way I'm glad because given my past no way would I have been a good parent.
