"Which do you like, coffee or tea?"
"I'm a tea person" or "I'm a coffee person" is a good way to respond.
In my case, I would say:
"I'm a Mocha person." (Mocha is my beloved beagle.)
The question is of course:
"Which do you like, dog or wife?"
Oops, I made a mistake. I made a typo. It is not 'wife', but 'wolf".
Please, do not say it to my wolf, oops. wife!
