Why do I see my age girls as, a bit older if they are married? I noticed a change in my tone at that time. Is this only me or happens everywhere?

I was talking with my friend. She was pretty cool. She still is.

But the moment I came to know that she married nearly 4 months ago, I suddenly, began to see her as a bit older than she already is. She is 22, but I saw her something around 24 or 26 somewhere near that.

And then I, involuntarily shifted my talking tone from a bit relaxed to a bit controlled one. As if, I was watching what I was speaking. A kind of respectful tone.

Has this happened with you anytime, or is this weird and exclusive to me?
