I saw you... (presumably) Mechanical Engineering girl who waved me down while walking on Mass Ave. I've clearly been your instructor or TA in the past. You were going towards campus and I was going away. You introduced me to your sister, who remarked to me that she enjoyed my writing and work which you showed her and who was thrilled to meet me.

All I have to say is: word. Also, I forgot your name. So terribly sorry. I hope you and your sister build super awesome things.
