After fixing a p*nct*re on a cold and rainy day, don't let the unpleasant conditions persuade you to ignore the fact the back wheel now has a rather drunken wobble on its axle. Don't then, in your enthusiasm to be somewhere warm and dry, continue to bang the same wobbly back wheel over 12 miles of south London's finest potholes. Note also, that grinding, chumpa-whump kerringCHA noises are not a sign of of well functioning, mechanical grace.
If, like the distant friend of mine, you did this, then you might find yourself relearning those childhood hub stripping and axle/bearing replacement skills at a later date.
