"New Shoes Again?!"

Whenever I visit my parents, my mum always looks me up and down and when she gets to my footwear she ALWAYS says "New shoes again?!" even if they're not new. Of course if they actually are new, I always deny it (especially if they were expensive... Or I lower the real price). I lie because my mum makes me feel I shouldn't be 'wasting' money on more shoes/clothes or other material things. Unless it's £10.00 or under. If I say my shoes were £30.00 she'll say "My god, I wouldn't pay five pounds for that!". Ahh my mum makes me laugh.
