My Sim must have given her between 5000 and 10000 simoleons. Then I complained once instead of donating. I think I got around 2500 simoleons back then. She got upset and hasn't called since, but via dialogue I can still fund a project. Last I did that, it ended up a no deal and got no money back. I didn't really care either way, as I always use the money cheat. But every time she called and I gave her 1000 simoleons, the friendship went up a great deal. I'm a little sad she doesn't call anymore...I was getting used to my boy funding her. Made it a special "friendship".
