To be a bit shocked at how suprised this woman was that I'm not married?

[Abbinob]

So at work we had someone in from another store covering someone's shift
We got talking and I was talking about DS, she said oh you look to young to have a a 3 year old (I'm 25 but fair enough i get this a lot due to big fat circle head of mine)
Then I told her my age and her next question..
"Oh so how old were you when you got married" explained im not and she looked really shocked at me and started asking why not, do I plan to soon etc etc i said no probably not right now and she avoided me the whole rest of the shift

Aibu to think this is really weird and rude? It's pretty normal to not be married and have kids these days right?

I think that often people get married at times of big life changes - first grown-up job, buying a house, having children, illness or bereavement, children getting older, children leaving home. I guess in long-term partnerships, a change big enough to jolt the long-term status quo is also a change big enough to irreparably damage the relationship.
