Dear Linda,

     We have some excited news for you. Maria is going to have a baby! We don't tell you right away.

At first the doctor said she might have some trouble of the baby. Now he says she is just fine. She still

works on his paintings every day. But she stopped from teaching her art classes.  There is going to have

another big change in our life. We're moving back to New York! It's very much nicer to be near the

families for something important like a baby. Maria grew up in Mexico, but she doesn’t have a family

here. So that makes even more important to us.

                                                                                                                Yours,

                                                                                                                 Dick
