He chose to go and do it now, even despite only having his siblings here. "Even if I don't want to choose one of them, I could just go outside."
He knew he had to come up with a plan to do it though, and think of where to go in. "I don't want to be seen, especially by my sister since she'd say something. So, getting in through the mouth might not be easy, unless someone's asleep... I think hiding somewhere, and sneaking in would be a good idea."
He thinks through where he could hide, thinking of places that could be decent. "Well, I could hide in the toilet in one of the bathrooms. Someone would have to use it eventually... Or maybe under someone's bed sheets? Though I guess sneaking up on someone from behind could work, would be a bit generic"
With so many options, and so many different types that could be chosen, he decided to think as he walked.
