Lena, I have too much things I have to say to you. But if I summarize it in a sentence, "You meant a lot to me in this life at Penn." Seriously, I am proud to have you as my best friend at Penn. Walking locust walk together every morning, Talking in your room late at night, imitating your mandarin and speaking to Marc. Talking about our private issues which was really special..... Gymming together, sometimes swimming, sometimes jogging, and the unforgettable day that the huge olympic pool was entirely ours. Shopping together, eating together...... I have too many memories with you and I can't help thinking that we can spend same hours again after this summer break. Actually you meant too much to me.....So special. We can't do things we did in Penn again, but I know I can see you again. Please keep in touch. And please tell me when you arrive safe in Taiwan.
