I have a good trick for you before I go on holiday. I call it, Knock Yourself Out. Dexter showed me this.
Let us say you have a back door and let us also say that the top half of your back door is see-through. This bit is necessary so that the person you are playing the trick on can actually see the trick. You hear someone at the see-through back door. Is it someone you want to speak to? No. It is old Mr Thompson who is not overly fond of you because of your youthful lack of backbone and dreadful manners. So, you approach the see-through back door with a charming smile and just as you go to open the door you kick it with your foot whilst also appearing to knock your head on the glass. Brilliant! You reel back and collapse on the floor and therefore do not have to speak to old Mr Thompson! After a while he will shuffle off muttering about feeble youth and manners or somesuch.
Warning: Some people might want to ring for an ambulance. If you hear screaming or shouting - jump up, brush yourself down and laugh. It all depends. I am very happy to hear about more great tricks like this one. I think I will put them all together in an informative pamphlet.
Meanwhile I am off to the land of the midge and horrible food for a so-called holiday.
