This is why my wife is my best friend... next up would be the pups and they aren't costly to entertain! :)
But thats just me, my wife fulfills all my social need and work does as well. Have a few of my college buddies that are out of state. Occasionally have a beer with my neighbors.
No need for bullshit "appearance" friends.
Sit around talking about how bad their life, kids, spouse, job, debt, etc is. Always talking about themselves or other people problems. Miserable way to spend a night.
I would squash this event request after they sent a link for a hotel. Absolutely hate wasting money on Hotels.
