The only thing more annoying than knowing that ALL of my clients have the day off work and still brought their kids in today (which means that I am missing my own child's performance in a school assembly), is that ALL the kids also have a cold. Snot everywhere, sneezing on everything and constant crying.
I should have booked the day off as part of my paid holidays - lesson learned for next year.
I feel like my frustration and resentment just keeps growing and I really need to find a way to get over it!
