Unilateral hearing loss (UHL) means that hearing is normal in one ear but there is hearing loss in the other ear. The hearing loss can range from mild to very severe. Parents or caregivers of children with UHL may ask:
The mirror doesn't flip left and right; it flips forward and back. Your front is farther north than your back, but your reflection's front is farther south than its back. Your feet and the reflection's feet both face down. The wrist with the watch is on the west side, both for you and your reflection.
At one level, the answer is simple. The mirror is not reversing the text horizontally. You are reversing yourself to look in the mirror to read it. To read a sign in the mirror, it is necessary to flip the sign so that it faces the mirror. If you flip the sign from left-to-right (around its vertical axis) the text will be left-right flipped.
