Maybe we could compose the voicemail collaboratively, and then I could just read it??

How about:

Hey B, it's T! How ya doing? I just wanted to let you know I got the key you sent in the mail. Thank you! That was really thoughtful of you and I really appreciate you doing that. Things are going really well here in Atlanta. And I hope you are doing really well too! I hope all is well with you. It was great to hear from you. Take care!

Something like that?
