Every year I prepare a small party for my birthday.
I buy a lot of things for this characteristic (? special ?) day, such as a cake, beer, lemonade, ice-cream, recorded music and a lot of surprises. But if I got a little more time, I'd prefer to cook a cake at home (OR to cook a home-made cake) than to buy one from the shop, because I cook delicious cakes.
I invite all my relatives to this party because I want many presents ^_^ Well, I'm joking.
I want to play either guitar or piano at this party.
What a prefect party!
P.S. Ali, it's a marvellous story! I am a bit envious of your guests =) However, in future it's better to use a "Notepad" function on Italki (instead of "Questions"), as it gives more opportunities for corrections...
