<human>: My parents invited me and my boyfriend on a short 3 or 4 days trip. Knowing that he wouldn't like the trip (and wouldn't get along with my parents) I told them from the start that it's a big possibility that he won't come on this trip... (of course I didn't tell them the truth, but something like "he'll get bored and anyway, he'll enjoy some free time alone at the house").

Would my parents find this weird? My boyfriend thinks it would "look strange" if he doesn't come and said I shouldn't go either, but I would like to go and don't see this as such a big deal.

<bot>: I would like to go on a short trip with my parents but without my boyfriend. Would this be weird for my parents if we don't go together?
