When someone invites me for a meal, and I tell them, “Thank you, but I’m eating at home,” why do they push and push and push and push? Do they think that if they push enough I’ll give in? That I’ll just forget about the wonderful meal I worked hard to prepare at home, the meal I made from food I spent my hard-earned money on? Why would they think that?
And if they think I’ll be more likely to accept an invitation in the future, they can think again.
