I found a vase left behind by the previous tenant and after giving it a wash and polish it looks quite nice so every other week I've been buying some cheap flowers at the supermarket and it's amazing what a difference they can make to the feel of a room. Currently got some white roses in there but we had yellow ones a few weeks ago and the colour was ostentatious but buoyant, a real moodlifter. I can only imagine a garden full of colour must be some buzz.
