I am extremely sorry for the late reply. The reason is that I got food poisoning and I was in a very bad condition for 4 days. I am still not feeling very good. I am very sorry that I did not answer your message earlier. Yes, I received your lovely invitation card but it was too late for me to apply for the visa. Thank you so much for remembering me. I am very sorry that I could not come to your birthday party. I hope you enjoyed the party very much.

I hope I can see you in the US next year. Do you have also plan to visit Poland? Do you know if your dad is in US or Turkey? Because I heard he was planning a trip to Turkey.
