I feel that the two main thing people look for when they look for a house sitter are consideration and trust. Therefore I am very considerate of other people's things and the value of them. No matter if it's a big or a small item, I make sure to treat it as if it was my own. Being that I have had a female housemate (who's is a stickler for privacy and respect) for four years, I know the value of trust. You're home will be look after and guarded as if it was my own.
