if you want to have some really good fun, you should plan it beforehand and chart it out in your filofax. thursday, 1800 to 2315: have really good fun. because if you just consider that you might have some fun friday evening, there will be an empty spot in your schedule and righteously beg for being filled with postponed tasks that could not be finished within their allocated time slots. and of course they won't be finished before their new deadlines either, because not later than the next evening you will have to go out and have some fun, arrive at home at about 2100 after having eaten something, still having to find fresh clothes, remove some excess hair, feed the rats and so on. in the end, neither seriousness nor fun will have worked out properly. as you can see, having really good fun involves taking it really seriously.
