Hehe... 21 years old liao... finally you guys also joined in the Club of 21s!! I'm glad that after 6 years of friendship (and roommate-ship in 2.2) hahaha.... we are still great friends! Viel Erfolg beim Studium, Sei immer glücklich und gesund! (All the best in your studies, always be happy and healthy!)
Have an enjoyable Birthday as you formally stepped into adulthood!
