How is it going? Haven't heard from you for a long time. I'm enjoying my new year's holiday here in Canada. I know China is famous for its colorful food. Since Chinese New Year is coming, what traditional Chinese food do you often have on New Year's Day? New Year is also a time to make resolutions. So what is your new year's resolution and why? My best friend Kate is traveling with me now. Both of us like traveling. Who is your best friend? Are you similar or different? Tell me something about your best friend, please. Yours, AmyTo: Amy200@outlook.comSubject: re: HiDear Amy, I'm very glad to receive your ema il. Sorry I haven't written sooner.
