It's 7:00AM. I get a message saying that the school bus will arrive in an hour. My kid's hunger bar is halfway empty, so I decide that an hour is enough time to have a quick bowl of cereal.
So, I pause the game (to make sure I can do all the input without any time passing), click on the refrigerator, select "have quick meal," and then "cereal." My kid, who just got finished brushing his teeth, walks across the house to the kitchen, grabs a bowl of cereal, walks over to the table, takes a seat, and then ... the bus starts honking its horn. My kid has to set the cereal aside and go to school hungry!
This is because, even though time passes in the Sims at a rate of 1 minute per second, and a variety of activities (including eating food, changing diapers, changing clothes, and bathing) are sped up to compensate, walking is NOT sped up! People still walk around the house at the same pace they would if time in the game went by in real time.
So, it takes an hour for my kid to just make his way from the bathroom, down the hall, and into the kitchen.
Even if I have Mom make waffles, and have them ready by the time the kid gets his teeth brushed, that still only saves the kid about six minutes seconds. Not enough time to actually have breakfast.
When the game says you have an hour until the school bus gets here, I'd expect I should have some time to do some more of my morning routine!
It's like I have to wake up at 3:00AM just to have enough time to shower, brush my teeth, and eat some breakfast! I should be able to do all of that stuff in an hour if I hurry!
