Dear Little Sims,
If I queue up an action for you, it's important and you need to do it. Do not drop it out of your queue and do something else instead. I queue up these actions for you because I want you to have a happy and successful life. It's in your best interest to comply. If you continue to defy me, I will lose my temper and things will go poorly for you.
Warmest regards,
Your sometimes benevolent Simgoddess
P.S. If you drop the action to read to your child to go get a drink from the globe bar one more time, I swear I will lock you outside in a blizzard in nothing but your underwear. You have been warned.
