I'm very pleased
I'm once again surprised by this person, a person who's so far away and yet we are so close. I'm glad that you care about me, and that you worried about me.
I' sorry that I've not been with you for so long, I'm sorry that I'm so weak when you might need help. I'm sorry that I made you worry about me, a person who is also so young to you.
Thank you for you care, really really thank you.
All the best to you.
