"My dear Fox, It is a very long time since I have heard any news of you; why have you not written to tell me how you are going on? - Are you turned idle, or do you think I am too full of South American bird, beasts and fishes to care about old friends?" Charles Darwin, letter to cousin W.D. Fox, July 7, 1837
Gone for 5 years, Darwin is back home and ready to connect with old friends.
