An awful discovery!!!

So today while I was brushing my hair I made an awful discovery, I noticed my first white hair. Naturally, I plucked it out and searched the rest of my hair to make sure I did not have anymore (I didnt in case you were wondering.) It just came as such a shock to me, I mean I am only 20 years old I am not suppose to have any white hairs!! Oh well there is nothing i can do about it now, I guess I will just have to blame it on all the stress!!
