We killed a snake

 Neither one of us wanted to do it. We first saw the snake, or one like it, in the garage. We showed the picture around and learned that it was a jararaca, and venomous. Then last night there it was coiled up on the stairs, inches from where Carol was standing. We shewed it away and did our research; 52% of snakebites in this country are attributed to the jararaca and they can be deadly. It was back this morning, curled up on the porch like a kitten. We shewed it away more forcefully, let the landlord know and did some more research: likely venomous, don't approach. It returned to the porch again and was shewed it again. The third time it returned to the porch, we didn't shew it. I dropped a rock on it and now it is dead. We aren't sure we did the right thing. We probably didn't. We like animals and it was a beautiful creature but we have a dog and he is a beautiful creature too and we are responsible for him. I wish moving to Brazil came with a handbook that provided some guidance for times like these.
