GEL,
Did you tell him that you will shoot for every other day?

I was unclear on whether you discussed it or just sorta figured that's how it would play out.

Also, I don't know about you initiating it. It's supposed to be HIS assignment. I wouldn't be so strict as to say that you can't do anything but it sounds like this could be a learning experience for him--one that he won't learn if you do all the work, kwim?
If he so much as makes a comment about it, I say go for it! But maybe not doing the whole kit and caboodle FOR him.

If you both verbally agreed to do it tonight, then I would send out "I love you and want you" signals but let him do the rest.

Just my two cents; feel free to ignore it if you feel that it'd be a disaster in the making.

Good luck!
