Friendship - Christian The Lion

In 1969, two friends, Ace Berg and John Rendall, saw a lion cub for sale in Harrods Department store. Cramped and lonely in a small cage, they decided to bring it home. A local vicar allowed them to exercise the cub, now named Christian, in the church grounds.

When they brought Christian home he weighed  only 35 pound. A year later the little cub had grown and he weighed 185 pounds. The only thing they could do was to reintroduce him to Africa, which they managed to do. A year later they wanted to visit Christian but were told that he was the head of his own pride and as such was completely wild and would not remember them. Undauntedly, they went anyway

And the rest you will have to watch for yourself...
