I am writing this letter to give you great news on my newly purchased house. I hope you are doing well and sorry for not being in touch for such a long time. I was too busy in moving to new house.

As you know, our old house was not that specious and had only two bedrooms. With addition my baby girl we needed a bigger house. Neighborhood was also not that great and it was very far from Ben's office. It took long time to buy this new house, but believe me this is great one! My son is very happy to be at this new house. We have 3 specious bedrooms, a big size living and dining room and a fully equipped kitchen. My baby girl has a great space to crawl. It has a small backyard with a pet house for our doggy - Raju.

More importantly, this new house is very close to Ben's office. Now he is starting late to office and reaching back home early. Ben is also happy to give quality time for us, instead of wasting his time on long travel and traffic jams.

This Sunday, if you are available please visit our new house; I am sure you will like it.
We can have a lunch together with our families. We will also like to get your creative ideas for decorating our kid's rooms. Please find the address as below.
