Funny Thing today - old classmate

About a year ago, i took up tax law class and i met this guy named Yves who was my seatmate in some days and he even borrowed my notes a couple of times to recite. Well about 2 weeks ago, i got a call from a guy named Yves asking about a tie-up with our company. After we had agreed to the tie-up, i asked for a meeting and surprise suprise! same Yves!! He got surprised too coz what happened was both of us didnt know each other's surnames. So, it never registered in my mind that he could be the same guy. In fact, i know we had a crush on the same girl too! That's the funny thing that happened today.
