There were times I would cry my eyes out for something and they will not relent. And sometimes I would absentmindedly say 'I wish I had X' and they would buy it for me. Like totally bipolar.
It made me bipolar. I deprive myself by only ogling at the electronics section. I pick the generic store brands that are 50 cents cheaper while shopping for groceries. Then all of a sudden I decide that I need a 70 dollar argyle sweater from Buckle because its totally awesome.
