Hi [imię]!
Congratulations on your new rollerblades! I would like to wish you a happy birthday! Fulfillment of dreams and prosperity. I hope this year will be even better for you than the last on and also I hope all is well with you, unfortunately I can't visit you as I have gone to my grandmother in the countryside and am helping her on the farm. It's beautiful here! Too bad you can't see it for yourself.
I look forward to hearing from you!
XYZ
