They are depressed and sick of you controlling them! They would rather die than to have you instruct them to do another menial task. The only cure is to turn off the game and allow them to live their lives without your input. go outside or something, for their sake and yours.
lol Decibel thats funny,but healnear you probaly need to check there depression and if that doesn't work than try going on a date and eating out at a different place
Hey. If you are on the sims 3, well im having the same problem! I have just updated my game that it tells me to when i try and get on my game. So if you have just done this then its the same as mine. I click on the fridge and i just says open. I cannot cook any food in the oven or have not items in my fridge like apples, cheese etc. I thought that maybe with the update that you needed to go and buy some food from the shop but i tryed this and its like all the food has been deleted from my game! Is this happening to you. I have been looking all over on the internet to see if anyone is having the same problem.
