The following are purely brain holes. Please forgive me if I have offended you.
"Brain" may represent your thoughts and "body" may represent your actions. Recently, you are worried that you have ideas, but it is always difficult to put them into action and you can't keep up with the people around you. "A" may represent your depraved heart, "food" may represent a hobby of yours, and "B" may represent the girl you like. You don't think you are good enough to catch up with her. You are determined to put one of your time-wasting hobbies behind you and try to catch up with her. But instead of insisting, I picked it up again. You feel guilty about it, so there is a question of B.
