Depends on where it is. In some places you need it, in some places you might as well do without.
Friction between parts you want to move is bad, it causes wear, generates heat and sucks up extra energy.
Friction between parts that you want to stay put is a good thing.
If you didn't have friction, pretty much everything would keep sliding around at the slightest chance. Open the door and the draught would have your furniture sailing across the floor.
It is harmful and can be extremely painful. Your bones should never rub against each other. You have cartilage, tendons, and synovial joint capsules to protect, lubricate, and absorb shock on your joints. Together they help protect your bones and keep things working smoothly. They help keep motion smooth, reduce pain, and provide protection. If your bones rubbed against one another, there would eventually be wearing down and fractures due to the friction ,and left untreated, can cause serious problems. This even happens in the vertebrea.
it depends. rubbing your hands together is friction, and rugburn is friction
Helpful friction
Friction can be harmful or helpful when driving, no matter what time of year. For instance it is helpful when breaking and it is harmful between bearing surfaces. The loss of friction between the tyres and the road during winter can be disastrous.

maybe friction cause it makes your shoes torn out sometimes
because it is natural
When a spaceship enters atmosphere it can catch fire due to heat produced by friction with air.
friction can be harmful because if you stick 2 objects to rub against eachother for to long it will explode

Yes, friction CAN be harmful, depending on where it occurs. If you'd fall and scrub your knee, that's harmful friction. IF your shoes are chafing and yopu get a blister, that's harmful friction. In a machine, if a bearing becomes warm, that's harmful friction.
it can be harmful when you buy shoes and they are to tight and if your books and binders are really rough and you have a hard time sliding them into your back pack they will rub and cause friction
it can be harmful when rubbed against skin
it makes our shoes get blisters

harmful friction is when friction can do harm or be a problem for example of this is if your skiing down a hill with grass you will have to much friction then you fall and get hurt :p
This could be harmful when you are trying to move something heavy and it doesn't move.
