The scenario described above literally (sort of) happened to me.
Last week, my friends decided to celebrate the end of OCI (On Campus Interview) over dinner. Of course, being the great friends they are, my friends invited me. Unfortunately, I was pre-occupied with SBA (Student Bar Association: the student government) tasks. So I told my friends that I was busy.
As soon I sent the my reply, I totally expected my friends to mess around with me by asking whether if I were going on a date instead of dining with them. Instead, my friends asked me if I was going to a callback reception dinner.
At that time, I thought to myself: OCI has taken over our live.
