*sigh* They always do that to ya'. Right after making you wait for so long, once everything is ready, they either just make it SO MUCH HARDER for you, or they just tell you "No".
...it's usually because of 1 of 4 reasons.
1) They were planning to screwing you over from the very beginning, and they were just stalling/making sure they didn't seem like total jerks in the beginning/didn't have the heart to tell you then.
2) They agreed with the idea at first. But as more time went by and the more they thought about it, the more they realized that they REALLY DON'T WANT YOU TO.
3) Everything was going great and they were great with the idea. Then something happened. Whether they got into a fight with one another, watched a news special on something related to what's going on, Christmas Spirit left them, looked in their wallets, started chatting with someone on the phone who gave them ideas, etc etc etc. When that something happened, they changed their mind completely.
4) Something... that I totally forgot what I was going to say. ^^;; Eheheheh... sorry.
So yeah. You either have to wait it out, or fight it out.
Most people choose the latter.
