"Why don't you work on <task>?" -- sure, in a bit. - 5 minutes later "don't you think you should work on <task>?" -- Yeah, but I'm not ready yet. - 10 minutes later "you'd better start <task> soon" -- Not yet. - 10 minutes later "don't forget about <task>!" -- I know! ... - 10 minutes later "why don't you start <task> now?" -- Please Stop ... - 15 minutes later "you'd better do task, you're running out of time" -- yeah I was going to BUT NOW I'm so stressed about it that it's not happening!
Honestly, it SUCKSSSS, but sounds like it’s time to manage up. Parents are stuck in the uncomfortable spot of trying to leave you to make your own mistakes, but also not let you fuck it all up. So show them you have it under control and hopefully they back off and leave you to be the adult you are!
