Hello Susan,
It was my pleasure. I really enjoyed picking out your birthday present and performing at the party, so I'm delighted that you liked it too. I'm flattered that you and your friends admire me, especially since I was nervous about playing the guitar and singing at your birthday party. Also, I hope you do great on your final exams at school. I look forward to spending more time with you.
