Somehow i realise, some gals who has not in a relationship before, they tend to be having not pleasant personality.

I have one colleague, at the age around 30, she is quite helpful at times. But when comes to some critical issue, i found that she can't put herself in the others shoes, another words, 没有同理心。She enjoyed people falling in the awkwardness situation. Typical type of people that 看好戏。New comer not so familiar in the field, asking for clarification, she will replied废话and turn around.
Isn't it rude for a 30 years old lady to have a response like that to a colleague?

I shouldn't comment her as without relationship before so she has this attitude,
I should comment,
perhaps, because of her attitude, she's still single at this age.
