It was my birthday. I and my parents prepared for a holiday. I was excited. I was slightly grieved because I knew that I won't receive a gift from parents on birthday. To us many guests came, I received a lot of attention. When we sat down at the table, I noted that mother and the father were gone I went them to look for. At that time I didn't guess at all why they left. I returned even more uneasy. And here loud squeal was distributed and light was disconnected, I strongly was frightened. The light wasn't turned on about two minutes. And at this moment at my ear something mewed. The light was turned on, I wiped eyes and saw that near me the kitten lies and looks at me tenderly and cheerfully. My parents nevertheless decided to present to me a cat. He had dark ears, and is a lot of gray, white and brown spots. It seems that it was the happiest day in my life which I remembered forever.

the beefeaters are most famous for their striking red and gold uniform, but they actually only wear this on fornal occasions . Most of the time they wear a dark blue uniform with red trimmings
No one is exactly sure where the name " beefeater" comes from.

И когда пишется This, а когда These?
