Hi Kai,
This is a picture of a clock with a sheep on it. The reason I want to show you a picture of a clock is because tonight in Scotland the time changes. very early in the morning, or maybe very late at night, the clocks will go one hour forward. We do this to make the amount of daylight when most people are awake to be longer. It has been done for almost 100 years. It also makes some people complain because they get an hour less in thier bed if they have to go out to work! I don't know if you change clocks in South Africa, but here we do it twice a year, once on the last Sunday of March to move them forward and then we move them back on the last Sunday of September, very close to your birthday.
Can you tell the time on a clock? This is an analogue clock and there are two types of clock. The other is called digital. A digital clock shows the numbers in a row like 10:10 and the analogue goes around in a circle like the one here. There 24 hours in a day and 60 minutes in an hour and each number on an analogue clock is 5 minutes. There are also two hands on a clock a big hand and a small hand. The big hand means minutes and the small hand means hours. So if the big hand is pointing to 4 and the small hand is at 2 that means it is twenty past two. Can you tell me what the clock would be like when it is your Bedtime or your lunch time?

Lots of love, Dad.
