Hello, Jenny!
Thank you for your e-mail! I love autumn too. In Canada (加拿大), we have an autumn holiday called Thanksgiving Day (感恩节). Family members always celebrate it together (一起). I will go to my grandmother and grandfather's house. My uncles, aunts and their children will be there too. Canadian Thanksgiving Day is in early October. In America, they celebrate Thanksgiving Day in late November. Have a good time on your birthday, Li Ming! On my birthday, I have a cake with candles. Everyone sings the song "Happy birthday". Then I blow out (吹灭) the candles! Will you have a cake for your birthday? Your friend, Jenny | ||
