Long awaited letter

My dear Friend sends me a letter. We have been exchanging correspondence for 20 years now. So we have a lot of pages written already. With each letter, we are sending something extra. So this time I've received a book by Howard Wandrei. Another one for my list of shame...

Now I'm in desperate need of free time to write him my answer. But before that, I must write another letter to my other dear friend and correspondent. Busy time for me between eleven and midnight for the next couple of weeks.
