Suppose your vegan friend invites you to a house party and he serves up veggie burgers. You can't stand them and only eat red meat. Do you attack your friend's character for being vegan or do you just say, "No thanks. Not for me." If you choose the former, do you expect to be allowed to stay?
You're describing an acquaintance not
When a FRIEND
invites me over they're sincere enough to serve something they know I and other friends would enjoy. If they are unsure about something they call and inquire. Friends actually care
enough to entertain you with something you'll enjoy. Likewise, as a friend I reciprocate.
It's an acquaintance who is most likely not give this much thought, and at worse - simply push upon you what they think should be your priorities. Yes - I have the courage to say "no thank you" when someone wants to serve me something which at best I don't want, and at worse won't tolerate. If you are eating food that turns your stomach simply to "be nice" you are not being authentic - and authenticity is a necessary ingredient to real friendship.
I'll continue to be authentic in everything I do, irrespective of how many veggie burgers the people who confuse familiar for friendship choose to serve up.
