1. Suse wrote: "Hubertus" (= going to Hubertus' pharmacy and pick up some special meds for Ada)
2. Andreas wrote (after he had picked up the meds): "accomplished"
3. Andreas re-wrote his message by changing all the vowels: "accamplishad" (actually different in German, but it's impossible to translate it) and added an "He loves his Suse" (also in that funny language).
4.Suse had to laugh and answered (wrote) in that language, saying she does love him, too.
Little things like these make an "US" out of "YOU" and "ME"!
