i may have a problem with my number thing. i always choose an odd number rather than an even . i won't get out of bed at eg. 8.04 and would need to wait a minute, while feeling slightly cross with myself for missing the optimum time of 7.59. listening to music i have volume 5 or 7 etc etc. anyway i had an eye test yesterday and the optician asked a series of questions 'which is the sharper image -number 3 or 4?.....5 or 6?.....7 or 8? i found it difficult to answer with the even numbers and even answered 'not sure' on a couple of occasions when really the answer was (not very)clearly another even.
