No, I would probably be pretty upset if I was in your situation.
Time to find some real friends!

Depends where the free trip is to. If it’s to another country then it was nice knowing you, to Walmart then that’s an issue. 😉

I would be more pissed at being ditched than anything else.

somewhat but who the Heck wants to go Camping at 61 years old , freaking Mosquitoes and walking a ways with a full pack-pack to set up camp and wait its not over yet , you gotta spend all day collecting Fire wood , oh wonderful , lol hope someone brought food and weed , toilet paper almost forgot and water

Depends how close they are to you

No

Not at all

Not really. [b]Better[/b] friends might’ve found a way to include you. 😒
