Coworker asked to complete a part of a client's implementation that I trained them on so that I can be freed up for other projects. Month later asks me to take it back over as the client wants it done next week and they are going on vacation. Completed none of the work and didn't follow up/resolve an issue that I explained when they took it over. Thanks for that.

Not a rant but as an intern that is older than several of the members of the team I'm assigned to, including my mentor, it was still nice to be complemented on my ability to find workable solutions on my own rather than running for help whenever there is a problem.

I thought it was rather weird to be complemented on this but apparently how I work isn't always the norm.

Coolest project I've worked on would be my CS final project where I created video poker.
