This was at my previous and last internship. At previous ones i never got serious tasks so i was pretty used to that but one day my guider (lead backend programmer) called me over to help him out with a server issue (in all seriousness he said that i was probably the best Linux guy at that company at that moment). So i fixed it quickly and just out of curiousity i asked what kinda server it was and how many visitors it got monthly!

"it's a prod server and about one million at least i think"

I was just standing there for a minute and then asked why the hell he let me, an intern, work on that to which he replied: because you know what the fuck you're doing. I think I succeeded in hiding the tears of happiness that came up at that moment :) i fucking miss that place.
