1 When you fall down and slide along a downward sloping asphalt road, face down, friction is harmful.
2 Writing with your Parker fountain pen on a poorly finished wall.
3 During space craft re-entry, atmospheric friction is an evil to the spacecraft and heat shields are a must.
4 When you try to unravel the knots in the wires of your ear phone, friction is such an annoying thing.
5 When you drag your nails on a blackboard, the sound caused by the friction can be jarring to the ears
6 When you make Dosa/Pancakes depending where you are from, if the pan is not a non-stick one and if you forget to pour oil beforehand, good luck fighting with it and removing the burnt parts on the pan later .
7 When you are learning to play your guitar and the sliding hand is very sore because of friction
8 .Inthe rail gun developed by the Americans where the high speed projectiles really wear down the track (rails) due to friction, requiring maintenance or a better solution: perhaps aided with a passive magnetic levitation system
