A lot of people don't understand why I am so obsessed with MAC.. I don't understand why my mum collects so many plates, when she has 1000s of them at home.. I don't understand why my dad collects so many CDs.. I don't understand why my friend collects cosmetic brushes, when she doesn't even wear makeups.. So my point is people like collecting different things and really, you don't need to understand lol
