I'm going to delete shared team files on my personal google drive
Why do you want to delete shared files that other people are using?
They're sitting there for a long time and I forgot about them.
You should let your team know before deleting those shared files. It'd be bad if delete them without telling them. Maybe they need them.
You are fucking stupid, It's my drive and their files are on my drive. I have right to delete them.
There's no need for hostility, I'm just trying to help you avoid more problems in the future.  Your co-workers might have though that this was a shared drive, since you had allowed them to store files there in the first place, so you should at least give them a chance to remove the files on their own.
