Well, the cynic in me that is me suspects that she did that to get her way. On the other hand, she's burned a lot of bridges, and maybe she just really wants someone to accept her.

...maybe google it. Suffice to say the birthday-ees act completely spoiled and entitled. And complain about things that other people would be ecstatic about, even if they got nothing else.

Maybe just do the dinner and movie, and maybe one more thing, so it doesn't seem like you're skimping, and you should be alright. I'd probably suggest a limo as it'd only add maybe 20,000 yen to the total cost. But maybe you'd prefer to treat her to a spa or massage... I imagine either would work.

But hey, just my suggestions. It's up to you whether you really want to even bother with her.
