When I was in Kenya , I got down to an anemic and unattractive 155 lbs . That was admittedly too skinny . But last weekend , while cat sitting for a friend with an electronic scale , I stepped on ( fully clothed ) to see a rather unexpected number : 206 .
Why were they at their friend 's house ?
Pick the best answer from the following options:
- they were taking care of the cat
 - they were watching the dog
 - to use their fancy scale
 - None of the above choices .
