I have bitten my nails my whole life (minus two disasterous attempts to grow them). Most of the time I don't notice this, unless I end up making them bleed and hurt. However, my lack of fingernails is driving me crazy today, and now I feel remorseful.
I have a new mobile phone. I put the back on it, and now I've realised it hasn't stored any number I've added in the last year, and so I need to take the back off again, and get the numbers back off my old phone. Trouble is, I CAN'T GET THE BACK OFF. I've been trying for about half and hour to do it, and have bruised my lip trying to prise it off with my teeth.
I feel like a rabbit trying to drive a car. :(
