Dear Ron and Emma,
Congratulations on selling your house! We know that you have been thinking about this day for a very long time and must be very pleased now that the day has come. I am sure you are excited to start looking for the smaller place you have been wanting recently.
Both of us envy you as you now will be able to free up the time once spent on maintenance and lawn care. We might buy the snow shovel from you since you will probably no longer need that.
Speaking of such things, if you want help planning the yard sale or with the apartment hunting either of us would be more than willing to assist. Let's get together for dinner soon.Sincerely
