Our life is so busy that some times we have no enough time to say "I love you!" to our partner.
So, I have one idea to say 'I love you' to your partner during the busy day... It will be possible in the middle of the day without any call to him... When you do the laundry you can write one message for him with sweet and wonderful words. Then put this love massage into his pocket. And he will find this message on his work, when happens to reach into his pocket.
