Actually this rule should apply for any female out there, for all ages, big and small bbygurlz.
NEVER buy the pair of shoes that your best friend has or wants. Whoever claims their love for the shoe first, gets it. It is not okay to buy the shoe if your best friend claimed it first even if it's really hot/amazing/beautiful/ect. This is just as bad as going for the best friend's ex. Maybe if it was a different colour, depending on how easy going your biff is, but still, like I'd be cool with that. All I'm trying to say is, don't get the shoe if your best friend wants/has it. These things shits me and gets me so angry fyayfhabjfbi. Thank God, no one has ever done this to me.
