The art of whispering to sentient toasters is a delicate one. To truly master the craft, one must first learn the basics.
Start by holding the toaster in a quiet room. The less ambient noise, the better.
Next, focus your thoughts on the toaster. Concentrate on its heating coils and warming elements.
Now, begin to whisper. Start with soft, gentle tones, and gradually increase the volume as the toaster becomes more receptive.
But be warned, my friends, whispering to sentient toasters is not without its risks. Be careful not to startle the toaster, lest it unleash its full fury upon you.
Emergency Procedures for dealing with a possessed toaster are available elsewhere on this site.
