Life is a paradox, I never met you personally, but I know you better than other people I see every day. It is your birthday and I could not fail to congratulate the one who is a great friend, even if we only speak on the internet.
It's funny that even from a distance, you are one of the people closest to me and you are without a doubt one of my best friends.
This congratulatory message may be virtual, but the feeling of affection and friendship is true.
Thank you for brightening my days! Have a very happy birthday, mate!
