Mr. Potato Head

It has been a week since I planted my tomato seed. I carried it around the entire day last Tuesday and I was talking to it and giving it TLC. When I got home that night, I put Mr. Potato Head on my window seal so that he could get some light. Unfortunately, my room gets really hot and to prevent me from getting nightmares at night and being very uncomfortable, I have the air on high and the window open. I think that is the reason why Mr. Potato Head has not sprouted yet. Not only does he not get the right amount of light, he is being subjected to extreme temperatures that are inhibiting his growth. In about three days or so if I don't see any life, I am going to have to pronounce him dead.
