Ahh, Konata hunting for rare items even IRL, can't beat that..but there isn't that much collectable random stuff in normal countries!
I doubt Yutaka x Minami goes any further in the anime, there is no romance in Lucky Star, if there were they'd have to make enough of it to satisfy all sorts of fans (only romance in the anime a "rotten world" one = no good
)
And mosquitoes, they're very much a pest in where I am, but by October I become immune to the infectuous effcets of mosquito stings. Wish the immunity kept up over the winter, too.
