Oomis: Sorry but I strongly disagree with this statement “If she is too sensitive to answer what is a very basic and legitimate question, she is not serious about wanting to find her bashert.”
She may have just had a birthday, and be VERY sensitive about it. She may have recently been broken up with by a guy because of her age, or had some other unpleasant experience related to her age.
Trust me, she is likely VERY serious about finding her Bashert, but is just feeling sensitive about her age.
Have some sensitivity, and be careful about how you go about obtaining this info (See my comments above). You can also ask other people who are close with her (other co-workers, friends etc, or ask for a resume).
