Eek Cag. If they haven't gone right through the paint and you can't 'feel' the scratch if will be a lot less work. Even some car valeting services can buff out shallow scratches.
Need I tend to agree with a PP (Life?) who mentioned 'working towards' meeting v the criteria. I guess it is harder for a visually impaired person to train to meet the criteria, so it might be a reasonable adjustment to have a lower threshold with a probationary period to meet the criteria. But only if more people can share the guiding load I guess.
Also yes, DD is a right PITA and if she was my first she might very well have been an only! But... she smiles at me so beautifully, even sometimes through her stomach pain , and the smile goes right to her beautiful eyes, and I melt. I feel very lucky to have her.
If you are just in Cambridge for the day then the best thing is to walk around and just enjoy the architecture. Check out the Backs along the river, with the lovely views. And mathematical bridge. And maybe walk around a couple of colleges, although they may have an admission fee. Kings is very impressive though not very typical. Especially if you can stick your head in the chapel. One of the smaller old colleges is probably more typical - maybe somewhere like Sidney Sussex. You could do all of that in 2-3 hours and still have time to find a decent pub for a pint 
Love did that come with a voucher /refund
For more delicious pudding?
Now eating my rather spicy sausage pasta. I forgot I had a mouth ulcer - very much remembered now
