Not having a car sucks at times, but boy is not having a car a great excuse for when I would rather just relax at home instead of going out to hang with friends and not look like a dick for actually not wanting to go.
"I'd go and all, and I REALLY want to, but I have no ride there and don't have too much cash left on my card for an Uber, my bad guys".
Only time it backfires is when a friend says "dude, no problem, I'll swing by and come get you", but my friends are usually such sticklers on giving people rides that that almost never happens.
