Estimates Memes

Project manager asks for an estimate. You know it'll take 3 months minimum, but you also know they want to hear "next week." So you do what any rational developer does: give them a range so absurdly wide it's basically useless. An hour to 11 months? Sure. Could be done by lunch, could be done when your kid graduates middle school. Both equally plausible depending on how many "quick changes" they throw in after you start. The PM will hear "an hour" and put it in the sprint. You'll be there in 11 months explaining why authentication "took longer than expected."

You spend three hours explaining why the feature will take two weeks to implement, complete with technical debt analysis, database migration concerns, and API limitations. The business team nods enthusiastically. Then they ask if you can have it done by Friday. The headphones aren't even plugged in. They never were. That "good point" they mentioned? They have no idea what you said. They're just waiting for their turn to say "but it's just a button" again. Pro tip: Next time, just say "no" and watch them suddenly develop the ability to hear.
