My sweetheart got sick on my birthday (yesterday), and as a result we couldn't share the special birthday cake he had made. So today I made a time machine out of a cardboard box while he was at work. I drew on pretty spirals and dots, and I put yarny, stringy, hanging bits in it. I made sure to write "Time Machine" on it, so everyone would know what it was. It isn't done yet, but soon I will put an arrow on that can point to "forward" or "backward" (that way you can be in charge of whether you go forward or back in time). When he comes home, we can use the cardboard box time machine in order to go back to yesterday and share cake on my birthday.
I wouldn't want him to miss my birthday cake. It only comes once a year, and really, when you think about it, this specific birthday cake will only happen once, ever.
Maybe I can use it to go forward in time before he gets home and make sure it goes over well.
