12. It Gets Caught On Your Bag Strap
This is particularly bad in Winter when you wear so many layers underneath your massive jacket that you find it difficult to bend your arms and therefore free any hair that gets caught under the shoulder strap of your bag. You either leave it there and walk slightly wonky with your head pulling to one side or you stand there in the street, struggling to free and untangle the hair that has been trapped by your backpack which people question why you carry in the first place. (Backpacks are cool).
