I kind of want to facepunch my coworker, but as I don't like to lecture other people for their choices and I'm not a violent person, I'll share with you all instead:
This particular coworker is in debt (mortgage, car, credit card, and student loans) and regularly talks about being in debt. We are paid bi-weekly and every other week she says something to the effect of "Wohoo! It's payday! I can go get lunch/coffee/craft supplies/etc"
She's also in her late 40s and regularly talks about how she won't ever be able to retire because she doesn't have any money to save for retirement.
Anyway, she just bought a dog for $5,000. I was like "What?!?!? Seriously?" She says they saved up for it...and I'm thinking, ummmm can you really call it "saving" when you are in debt? And now that $5,000 dog will continue to cost you more money for years to come. Plus they already have several other pets.
A few weeks ago they also bought one of those mini pigs for like $500, but they ended up giving it back a few weeks later for some reason...so they were just out $500 for that.
