presently in my (quite small, I don't like the thought of lugging one of those huge bin bags around!)
£2 Jasper Conran from the local charity shop 
handbag -
home keys, shop keys
(oops other guy should have these!), phone, trident lemon gum, bottle of lucozade alert, almost full pad of pringle post it notes - with some scribbles about stuff to order for the shop & stuff to research for my boss, huge Suzy Smith purse, paracetemol, couple of hair grips
(useful for picking locks if, er, the situation arises - sorry, grew up on Marsh Farm estate 
), hairbands, nail file, couple of pens, nail varnish (just incase I chip a bit), and some catnip drops! No wonder all the local cats flock to me

Jo, I am going to nick your idea and get a spare inhaler for Anton and carry it around - and a spare lanzoprazol (?) for those frequent times he's forgotten to take that too
