Feeling not so groovy

Why is it I wake up today feeling horrid and still have not much of a voice and the start of a cold. Of all days, why a day when I have a job interview and have to go and impress someone, how can you impress them if your sniffling and reaching for tissues. Oh well I can only do my best and hope that is good enough. Then I can come home and curl up on the bed for the rest of the day.
