Translation of unempfindlich

This is almost six hours, a long time for someone who has children and a day job. I recommend that we write eachother shorter emails and in both languages. Spanish and English next to eachother.
it was great talking to you. I am so happy that you are married. Here are our pictures. Please send me the pictures of you, your husband, the wedding and of course of your baby dog Vasco.
Your offer seems interesting to me. The language exchange is one of my future projects, so that we will contact you later when I am ready to discuss the ways and possibilities of learning together.
