This is a guide on how to be sneaky around the house.
1: Wear socks. Socks will not make a clanging sound on hard floors and will slide over surfaces.
2: Open doors quickly so you do get any squeaking. Also, never shut a door unless you absolutely need to.
3: If you hide: stay still, from my personal experience if you don't move people will not notice you. Everyone has a tendency to ignore everything that doesn't move.
4: Know what will happen before it does, like if your Dad will wake up at 7:00, make sure you are not near his room at that time. Or if a object will make a noise at certain time, mask your noise with it.
5: Never use a flashlight in the dark, instead wait untill your night vision kicks in then you will be able to see perfectly.
6: If you can see someone, they can see you, so try to keep from looking around while hiding.
7:Never wear black. Solid black actually stands out in darkness.
All of these tips are from personal experiences. Most are from being on this site at 2:00am.
