Doing it on my own

So unfortunately I have been sick with the shingles and I do not want to infect my consultants children with chicken pox. So whats a girl to do? Well the obvious I have to re-tighten my own hair. I have already done the top portion of my hair but I have yet to do the back part. It took me about 4 hours to do the top so that means about 8 to do the back because I cant see back there and ti takes me twice as long to lock my hair. My roommate said that she will do it for me if I teach her which sounds like a great deal...we shall see. Lord please dont let me mess this up!
