She tells him she hopes he will do something important soon so she can join him. She wants to be able to tell people thank you in person.
She is planning a vacation to Guestrow, which I hope she does, I think she has family out there and it might be nice for her to get some country air. She seems happy today, in light of Opa's birthday. She has students she enjoys tutoring and family who love her children. She even has some energy to nag Opa to write her more. Which he really should get into the habit of at least writing a little note weekly. I'm kind of on her side on this one.
Happy Birthday Opa, I bet your 21st was very different from mine.
