Candles on a birthday cake.

How many candles do you put on your birthday cake?
I planned a surprise party for my husband's birthday.
That day was the eve of his birthday but it was the day my husband and I had planned to meet my friends from Australia in Kyoto. I decided to take a chance to hold it (I don't know what you mean here). I exchanged e-mail with my Australilan friends .
I booked a good Italian restaurant and odered an additional birthday cake for him.
We usually put candles of the same numbers of ages on a cake and after making a wish blow out all of the candles.
But my friend's husband has a unique tradition for it. In his family, they put only 3 candles no matter what your age is. And after making wish, they blow out 2 of them and leave one being lit.
The three candles means past, present and future and he blew out the 2 candles which mean past and present.
And it implies good luck if the last candle, which means future, can keep staying lit long.
What a good tradition it surely is!

Well written!  You just need to work a bit on spelling.
