I have sleep apnea, so I must wear a c-pap mask to bed every night. The mask has come up with a new trick. Right after I went to bed, the suction broke on the little rubber thingy that goes over my nose. When it did, it made a sound that sounded like a trumpet. I told my hubby not to get excited if he heard that in the middle of the night. I didn't want him to think that the trumpet was blowing for the Rapture, and then be disappointed to find out that it is only my mask.
