For me I think it was the first semester of my 2nd year of University. I was staying with my best friend at the time and it was my first time staying away from home so it was like a permanent sleepover. We would talk all night, laugh, I would hang out with her and her boyfriend (they didn't seem to mind me being the third wheel) but still be studious when it counted. I really miss the days of friendship but also not being sick.
