Have you ever surprised an omnivore that what they just ate is vegetarian?
I don't mean that you lie to them more that they assume that it is meat.
For example, sometimes when I invite someone for dinner it's not formal, just like" come and eat" . I never introduce the meal just put it on the table. So when they say "these are some great meatballs" I just... "Ehhh there not meatballs"
So have you ever "tricked" someone like that?
