I think some days are just like that and you have to go with the flow. Just 'be' for the time being and let it pass. I remember saying to my DH, when trying to persuade him to retire and he was asking what he would do with himself, that some days are just that - days when it's difficult to feel motivated. I'd definitely try going for a walk though, even if it's only round the block or to post a letter. There's a thought! Write a letter (a proper handwritten letter) to someone - a grandchild maybe? xx
To think that London, or anywhere else for that matter, does not belong to any one demographic
