Write a letter to your friend telling him why you couldn't attend his birthday party​

dear friend,

i apologize for my absence from your party. i couldn't show up because i wasn't finished with my 40 hours of violin practice. unfortunately, your party schedule badly collided with my practice time. obviously, i chose practice over celebrating your birthday. maybe next year i'll show up with a gift.

                                                                                                      sincerely, me

i can you there : )
