Hating your sig other’s ethnic food
It happens.
Doesn't have to be a big deal, of course. But when you are seeing someone who really enjoys his or her family's traditional ethnic food specialties, it can require some tact to find a gentle way to say you find it vile and want it nowhere near your open mouth.
Chances are, you are not the first person from a different tribe to express a lack of enthusiasm for the exotic fare in question. But because romance is involved, you might think you need to tough it out and gag down the special treats his or her mother or uncle serves.
That seems like a mistake.
Sure, you want to at least sample the offerings. But if you quickly realize you can't take it, playing the self-blaming "It's my parochial taste buds/not this tantalizing food" card makes sense.
