Firstly, please do correct me if it is not right/respectful to use the phrase ‘plus-sized’ as I am unsure of how it would be taken as, in other countries/cultures.
Sometimes I face the situation and have seen people face the situation where, I am sitting on a priority seat and a lady boards the train and stands in front of me. I am unable to figure out if she is pregnant or not.
I am afraid that, if the lady is not pregnant and if I give up the priority seat to her, she might feel insulted (again please kindly do correct me if this is not the right choice of word).
Therefore, how can I offer my seat to this person without insulting them if I'm wrong about my assumption that they are pregnant?
Edit: In all the situation that I have faced so far, the lady does not feel uncomfortable to stand. They seem fine.
