Dear Sam,

Long time no news from you. I hope you are doing great. I could not forget the time we were both had more time to hang out and enjoy the life. I might come to Budapest in September and I would really like to visit you if you are available that time. I will inform you whenever I come to Budapest. Actually, I have no clue if you are still in Budapest or not?

Have great time pall where ever you are now.
