This Broken Chant

I try to time my opening of the microwave to the exact second before the timer goes off. Sometimes I miscalculate and open the door a moment too late. Can someone invent a microwave that stops beeping after the door is opened? I get it, you are done heating my goodness. This is why I opened the door. Are you letting my roommate know that I am ready to eat? If so, he doesn't care. Let me enjoy your warm creation in peace. Yum yum.
