What is that noise?? Which one??

I was awakened at 3 AM this morning by Mark asking me what that beeping sound was. I listened and finally said that I did not hear anything except the man singing Karaoke. At this point I had not checked the clock and thought it must be early because usually they stop the singing around 10:30 or so. We have the air conditioner on at night so we don't hear all the noise and can rest comfortably. Mark insisted that every minute or so he was hearing a beeping sound. I finally heard it and said that it sounds like my cell phone is dying, but it was very faint. I rolled over to go back to sleep but he got up and said he could not sleep with that sound, and asked where my phone was. I finally remembered that I had left it on the table in the kitchen and thought, he has trouble hearing small sounds how on earth does he hear that, way out there when the air is on and the door to our room is closed? Then I saw the clock and it read 3 AM. What fool is out there singing their lungs out at this time of night? Then the church bells started ringing and then the cats started fighting. By now I was on my way to being fully awake. My next look at the clock showed it was 3:30 and no bells, no singing and no cat fights. Peace at last, now what do I do to get back to sleep? You just have to love this country !!
