Where are common places to leave an iPhone?

I lost my iPhone a few days ago and have been searching my house nonstop. I'm certain it is in my house.

Sometimes, the most unthinkable places may be holding your phone. Check your closet, your refrigerator (yes I know people who left it in the fridge), under your bed, in your pillow case, under your sheets, under the couch, in between couch cushions, coffee table, computer desk, laundry station, dryer machine, pantry, under your car seat, dirty clothes hamper, shower. Good luck!

Also check if your iPhone had Apple's "Find My iPhone" app installed. In which case you can log onto: https://www.icloud.com/....com/#find and use The iCloud web application that you can use to locate, play a sound on, track, remotely lock, or erase your lost iOS device or Mac computer.

Pocket of a pair of pants or Jacket. Check the bed and under pillows. I used to leave mine there.
