A few things about language, that I think could be fun to share.
What you call "fly screens" we call "mosquitero", which means "for mosquitoes". The word sounds a little like the Spanish version of "muskeeter".
Fireflies. The "proper" Spanish name is "Luciérnagas" but the common, familiar name, is "bichito de luz", which translates as "small lightbug". I love that name.
