The last time I saw E and M, they asked me about it and as I had not seen Yoko in a about ten days, I waxed sentimental. We really missed each each other — this and that. So, upon returning, I demanded that Yoko start telling me that she loved me every day.
Yoko, being the who she is, finds this no trouble at all and sometimes says I love you several times a day now, so as to not have to say it for the next couple of days. Sort of like an I love you reserve, but me being the busy person that I am, I felt it was easier just to write it on a piece of paper, pin it up on the wall, and point to it whenever either of us feel the need for affirmation of our love.
