When I do any house sitting I set out to genuinely care for the house. I don't like using much of what is available to me. I tend not to cook very much so many cooking appliances etc are not touched by me.
I am happy to use food that has a "used by date" that means it will be of little use when the home owner returns, and I like leaving the fridge with some fresh milk at least for when the home owner returns home.
I like gardening so I endeavour to not only keep plants alive, but I like them to look refreshed, so some things I carefully prune. I dead head some plants - at least with the dead blooms gone it looks much better. I don't touch things that I am not familiar with, or that I know are precious to the owner.
I do like to leave things cleaner than when I came. I have a few little tricks up my sleave that I don't sare with anyone, but I have the confidence in knowing I have made a difference. Curious? No, I'm not saying.
I'm careful to replace things EXACTLY where I found them - there's nothing worse than having your cupboards "rearranged" by a guest even if it was not intentional.
I hae just over a week left here. I'm "on top" of things, so there will be little extra to do as I leave. But I will ave the windows open so that there is fresh air, and I will endeavour to leave fresh flowers too.
