Jim said it best, people are strange - and thank god for that!
Imagine if we were all the bloody same. What a boring world it would be.
Individuality is what makes our friends and family unique and is also the reason we love them.
Sure they might be annoying or do things that concern or trouble us, but at the end of the day they're just strange in their own way and given the option we wouldn't change them for the world.
So embrace the strange, the wonderful and the cooky, for our lives would be far too much mundane without them.
