When I worked in an office, my coworker Maria was one of the nicest people on the planet – the kind of person everyone in the office genuinely loved – so when I organized her baby shower, the usual $5 chip-in turned into $10, $20, and one guy handed me $50 cash without blinking. Before I knew it, I had $800 in an envelope and a big problem: her giant family had already swept through her registry and bought all the big stuff.
