I, ah, often play for a dozen or so in-game days, so that may be part of why I found the "food is on its way" issue O:J (Also, there are some lines from Arlene that I normally don't see until the fourth or fifth day, and I planned on watching every movie with May.) I'll check tonight whether the timing is related to meeting Arlene, as Dig-Bick found.
I do remember getting another line via "talk" to May, and I think that time the food came before I could ask about her game collection(love the things she has to say about some of them :3), so maybe clicking on the games puts that one "in front", and it never completes so it never leaves the front? I'll try it tonight.
Listing the gender-marked lines was more intended as a reference you could look at when you do implement the choice. Games that retrofit gender choice tend to leave a lot of things still assuming male >_>
