I'm glad you can go to Shoujoucon! Just keep finding little ways to help him see that you're growing up, and he'll notice. ^^ Besides, eBay can be a dangerous place (not in a literal sense, you know what I mean). You can easily get a Gigi at Shoujoucon, or at an online store; maybe he'd feel better about that method, you could suggest it when you think the time is right. ^^
