Dear Joan,

Thanks for your letter. I'm sorry I couldn't answer you earlier, I had to prepare for an exam.  

It's sad to hear that rain always catches you off guard. In my city the weather in summer is mostly cold and rainy, there are rarely more than a few warm days every month. When the weather is bad, I usually stay at home and play computer games or my guitar.  

It's a pity you have to take your shoes back to the store. Did you get the wrong size? Are you going to get a refund? Are you planning to buy a different pair?  

I'm sorry, but I have to leave now, it's time for me to walk my dog.  

Looking forward to hearing from you.  

Best wishes,

Eliza
