False promises

I hate them. I loathe them, in fact. I realized how much when I went with my mother on Saturday to visit a great-aunt of mine. On the way back, we stopped somewhere for supper. She then proceeds to tell me that she thinks she and my dad will have their debts paid down, have some money saved up, and be able to put a downpayment on a one bedroom condo somewhere.
I have a problem processing this, mostly because this promise has been made before. The only difference was the building the condo was in hadn't even been built(it's still not done), and buying it was going to be a joint effort between a sister and my parents. It was also going to be a "micro-suite" that I would have been renting. That fell through, mainly because my parents didn't realize how broke they were. I am not angry that the condo wasn't bought. I am angry that the promise of a condo for me to live in and rent was made in the first place.
