i cant seem to touch my toes!

after 2 months of yoga i have come to be a lil embarrass about something. i can do some of the slightly more complicated poses with no issues - i can get into the pose and hold that position for over a min. like these poses...

however, bending forward to reach my toes or the floor kills me. i just cannot touch my toes! and my finger tips touch the floor but nothing more than that! i feel like some short dwarf who cannot bend over to touch her toes in class. :o(

BUT yoga teachers say to be patient with your own body and not to get frustrated...hmmm. i just thank god i always chope the back of the class so no one can see me reach my toes as if i am reaching for my dear life.
