Human Souvenir

You just visited the earth and got a famous 'Human Souvenir'. Would you be able to keep your human alive enough time to see them through their whole life cycle? You just returned from a vacation in planet Earth. You wanted to stay longer, but you did not have any more vacation days left... Instead, you bought a Human Souvenir to relive your memories of interacting with Earth Humans. And, of course, to impress your colleagues that you own a Human now.
