I should know better

It's very frustrating trend that going out to run errands in the morning seriously stresses the completion of daily tasks in a timely manner. Another equally frustrating trend is that the everyday tasks (read the kids school work) basically do not get done when company is coming in the evening. In what reality would both of these activities be compatible? When planning this day; a day with shopping in the morning and company in the evening; why didn't alarm bells go off? *Warning, warning* stress overload. Things will not get done. *Alert, alert* please revise your plans now to avoid mental anguish and guilt. Blah!
