It can be cute when kids start to shun some "childish" things to feel a bit more grown up, and that's a little too easy when someone else is the target. That makes Milagros' and Betty's self-awareness all the more special. In a way it feels as if they had this realization because they didn't want to think poorly of Wilfreda.
(…o quizá le estoy dando muchas vueltas.)
Whatever the case, thanks for sharing this poignant moment in the girls' lives. It's always a pleasure to see.
As for Milagros and Betty... they certainly don't want to think bad of their friend (Victor would, though), but they also realize they're playing with inanimate objects of their own. Kind of "yeah, okay, we're shooting our own feet" (with water pistols, of course; I would never give them real guns).
Also, a little trivia: this is not exactly how the comic was going to be. In the original version, Milagros was holding her tablet, making it look as if she regarded it as an inanimate object she took as "real", but in the end it felt a bit weird and I switched to dolls for both of them.
Thanks for the comment!
