wait so if i dont have all the courses and odne chores i cnat kick eric out using kates mom?
Yes the triggers did not go off so that means you must have cheated and you can still get them to go off but you will need to do them before you get rid of Eric.
Cheating stats bypass the trigger points in the game so they do not go off.
Cheating with your family does not allow the triggers to go off.
Alice, getting her spanked 1 time in the beginning of the game is a trigger. (I forgot what it triggers but it is a trigger.)
Lisa, getting her spanked 1 time allows 2 triggers to go off, 1 do her homework without error 6 times gets 1 relationship point and 2 allows for the convo about the candies that you need to give to Alice on Friday's.
All 4 on line courses have trigger points that go off for other quest.
Only thing you want to cheat is money to make sure you get the clothes before Eric does, after this you should not cheat until you reach 100 points in the skill because all trigger points are within the first 100 points.
