Does she do this a lot? That seems like something you’d avoid doing. I mean yeah “Whoops I broke the lock on the window because I pushed up a little too hard” is nothing, but uh.
The force to snap a lock is going to seriously injure someone with a handshake or hug.
Unless she routinely has some kind of ‘Power Incontinence’ controlling her super-human strength, I don’t believe she’s in the habit of accidently injuring people.
