Stalking....really. kind of an art to it. You have to kind of move when they move ...watch how they step..and watch your breathing..it can be learned...I think you can find it in an old commando manual somewhere. check the link below, they might have some books about it.

the person behind you. no matter what, the person behind you should have been paying enough attention to avoid hitting you.

By right clicking on that person's IM and clicking on Stealth settings and then making yourself invisible. Just be sure not to delete them or else they will know you're online... (This will only make you invisible to that individual person)

u r doing the right thing. if you "talk", your opponent can blame you for distracting him. I find that complete silence is even more irritating to your oppenent because they know you are being quiet on purpose. also, always stand or sit out of the oppenents line of vision. that gives then the creeps because they keep thinking you might bump them accidently, or ever so lightly on purpose. don't do anything that could bother your opponent. it will backfire.

First of all, if a person is doing you harm behind your back , that person is NOT a friend!!\n\nPeople do vicious things to other people for various reasons.\nFind out WHY he is doing this.  Then find a compromise or common ground the both of you can agree on to stop this from happening.  By doing this you can create a win-win situation, which will improve your reputation among your peers, and prevent further damage.

Yes you can. you need at least three or four people. One person follows the mark as far away as possible while still being able to see them, The other three then stay well back but still being able to see the first guy, but not seen by the mark. Then every so often the person who can see the mark just switched places with the three tailing far back. simple

change your status to invisible, then nobody will see you, unless that doesn't work either

yep-i think its a "6th sense" kinda thing...But wouldn't you rather know someone is there instead of them sneaking around?

Do you mean a silhouette? If there is a high contrast between the person and their background, you can first desaturate the image (grayscale), then use the Threshold algorithm, or the Brightness/Contrast control in your image editor to totally obliterate all features except for very dark regions and very light regions. You can modify this to be smoother and so on afterwards with other tools.\nIf there is not enough contrast for this to be effective, you will have to select the person yourself. The QuickMask tool in Photoshop, along with the Background Eraser and the ability to make masks from color channels are great ways of selecting out hard-to-separate objects. See http://www.graphic-design.com/Photoshop/tutorials/quickmask.html .

The first thing you need to do is to make sure that none of the light reflected from your body reaches the observer.   The observer would see a black object there (you).  So you must replace that light with the light that the observer would normally see if you were not there. So I would guess that you must bend the light that is coming from behind to bend around your body. \n\nHow you would do these things, I have no idea.

Similar to Astro's answer, you can lay down on your back and have someone else stand with their feet behind your shoulders.  (Your head will be between their feet.)  Hold on to their ankles or legs and, while keeping your legs completely straight, lift your legs to their chest.  At that point, your friend will push your legs back down to the ground - but don't let your feet touch!  And keep doing it -- raise your legs/have them pushed down/raise your legs...It really works!
