If you have an avenue lined with trees such as this you are truly blessed. Even better, if its partly remote from cars.
Use it! Go for a picnic, bring a friend, rug, grapes [ha!], lemon meringue pie, your camera [a must]and bring a rope, climbing trees is a truly lovely pastime.
And this is the first step to being more lovely, from here you can sit and think of all your own ways to be more lovely.
