Your cat rejects a can of tuna cat food

She ate the can of ochicken flavored food you fed her last night, and the night before.

Your bedroom air conditioner blows very cold air at night, but only cool air during the day

Your bedroom gets lots of direct sunlight all day long

You're talking on your cell phone in your bedroom, when suddenly the reception goes bad for a minute

Just before the reception clears up, you hear the microwave beep in the kitchen.
