When your lover is in jail, he has plenty of time to think about you and how much he wishes he could be with you. Sending him letters soothes that want until your next visit or until he is released. The more intriguing your letters are, the more enthralled he will be. Don't write just to write -- let your heart out and some time later he will receive it. In addition to writing letters, you should also call him at least once a week. This shows him that you still care and that you haven't forgotten him. If you would like to send him something special, then consider sending him books from the library of materials related to prison life. This will allow you two to talk about what you've read and engage in a discussion about issues such as crime and punishment. Your relationship will be greatly improved by your involvement with each other's affairs while he is incarcerated. Take time out of your busy life to focus on each other and show him that you care.
