the microcentrifuge that i usually use was occupied, so i walked over 2 bays to use another one. and as i was pressing the open button i realised that it looked exactly the same as the one Wei had. the one that was broken. my heart literally missed a beat (:p). i know before i left san diego i said i wasn't sure if i was going to missed anyone or anything there, but sometimes nostalgia creeps in without me even noticing it.
