Oh so shocking! Such little minds go right to they must be selling themselves you know how girls are, huhhh huhh! Maybe they saved up for the trip, or got a gift from a family member for Christmas.

Right omg I’m surprised but not surprised at the same time like no one considered internships, saving, peace corp, mission work, a work opportunity, travel hacking, maybe the put it on 💳 and will pay it back with tax return, maybe it’s off season 

People share what they want to share, maybe they didn’t want you to know they do have some side hustles going.

 I think it’s extremely weird that you know so much about their schedules/lifestyle and hangout regularly only to be blindsided by this trip. Are you on the outside looking in, maybe social media stalking. Maybe they just don’t consider you a good friend 

So many people don’t share travel plans, especially not with casual school acquaintances. Smart people don’t update socials until they get back for safety issues if at all

Op is just jealous they didn’t get invited 

Nope it’s a women so she must be selling herself in someway
