Thouse "sports bottle tops" or what ever they're called i cant stand thouse they gross me out. It even took me a while the other day to find a bottle of water without one.
Id get rid of all the kids that come to my door and constantly ring the door bell and knock the door untill you answer then they say "my ball/frisbee is in your garden will you get it for me" Grr drive me round the bend.
