Hey! My roommate has Apple TV and I guessed her password and can get on the wifi on my laptop. Does it cost her money if I get on the internet a lot using her wifi? Or is it just floating around and I can take it if I want? I'm just wondering, cause if it costs money the more you use like a cellphone plan then it would be pretty bad to use it... She's not here right now, it's not like I'm slowing things down for her or anything. Help? Thanks!
