Friend: Hey, can you fix my laptop? The hard drive is almost full.

Me: (Looking through his folders) Maybe it's because of this. Why do you have 3000+ files in your downloads folder? Maybe I should delete some of this.

Friend: No no, please don't touch the downloads folder, I have some very important documents there.

Me: Why don't you move them to a separate folder then? You should organize the ones you actually need and delete the rest. This folder is a complete mess.

Friend: No no, the problem is not the downloads folder, there must be something else. Can't you just uninstall some programs to free up space?

Me: I could, but I don't know which ones you actually use.

Friend: What? You should know!! You studied computer science for this!!

Me: First of all, there is not a single class in the whole 4 years of university called "How to uninstall programs and free up space on 128GB hard drives of shitty €400 computers". Second of all, I don't know why you were expecting me to find a magic button on your laptop that immediately frees up all the space in a hard drive without actually deleting anything. That's not how computers work, you know.

Friend: Hey if you didn't want to help me you could have said so in the first place.

Me: FML
