Why does my hairdresser keep telling me to become a model??
My grandmother told me I should just drop out of college and become a model... I'm not a model material...
So, I been invited twice within this week to join a modeling call in February by a local photography company. Should I attend?
So this girl I'm friends with on FB was helping the lady she models for look for new models and I gave her my info and now all I can think is "fuuuuuck" because I'm probably just making a fool of myself.
