Your 21st is known as one of the biggest birthdays of your life. It's known as the age you get the keys to the door, however this statement has never made any sense to me as when I lived with my parents, I got a key to the house when I went to comprehensive school and since September last year, I started to rent my own flat so the whole 'key to the door' for your 21st doesn't seem relevant to me and therefore my birthday this year didn't seem to matter all that much to me. I didn't see it as special or anything... Of course I still wanted to do something on the day but I never gave it much thought. See, I'm pretty sentimental when it comes to birthdays and holidays like Christmas or Halloween so I have to do something, even something small. However, what I didn't know was that my 21st would turn out to be one of the most exciting birthdays I've had.
