But i am happy the small hedgehog kid made it throught the winter,
all on his own!!  And came back with a girl friend: "Frühling!"
(Spring!), as if it is the simplemost thing on this earth!!
I now call him "Riccio", "mein wunderbarer Held!" ("Hedgehog, my
wonderful hero!").  Yes!!!  (I just hope he is always careful with
the many cars.  You know, these two legged are a real problem.)
