Will peter still come even if tu have a fixed net over your window?

Ok, so i have a fixed net over my window. Will peter still come? What do i need to do to get him to come? I sometimes sleep with my parents and sometimes in my room with my sister. I always say i do believe in hadas i do i do in my room siguiente to the open window. I never say it in my parents room. Will he still come? Hopefully yes!
