You're having one of those days.
Everything's coming at you all at once. Paperwork is piling up. Emails are screaming to be answered. Phone messages have yet to be returned. Contracts have to be signed and shipped off in the mail. The family room is in desperate need of a couple runs with the vacuum cleaner. One of the kids has a permission slip that needs to be signed like right now.
Sometimes you need to walk away.
Just remember to come back.
