You don't. Just avoid them, don't flirt, don't laugh at their jokes, and they'll eventually get the picture. Don't be too obvious about it; don't be rude, just boring. But there are always people that just won't give up. As a last resort, you could ask a friend to tell them for you. Have them just hint at it. DON'T have them say "hey, Samantha, Fred told me to tell you that he doesn't like you." And pick someone that is good friends with the person; someone that the person trusts. Another thing you could do is make up an excuse. My excuse that I use often is "I don't date younger girls", which is partly true. Another thing you can do is talk constantly about other girls (or guys) when she's (or he's) around you. Just be like "Wow, that girl (or guy) over there is hot" or "I miss (either your ex or your crush's name goes here)"
to tell someone you dont like them is very easy if your not interested you could simply say you just want to be friends or that you like someone else if the guy/girl likes you enough they would accept your decision and understand that you like them but dont want too be official like them ;</P>
Seriously just flat out say that you really don't like them at all and then just walk away. Nuff Said.
There's not really a nice way to do it but here's what I did...
after they ask you try to avoid them and just ignore them completely. if they keep bothering you about it continue to ignore them. if it's been a while and they can't take the hint just have a friend tell them you said no OR the next time they ask you about it say can you not take a hint? just try to seem sincere and don't be a jerk
If you aren't ready to date, you can tell that person that you simply aren't ready. You could be honest, but don't be too harsh. What ever you do, do not lie. Lying will hurt you in the end. Good luck!
Be polite, honest and straight forward. Simply tell them that your flattered but sorry you are not interested in them the way they are you.
tell him/her you dont like that person
Just tell them you dont want them and if its someone who you dont like getting emails from, block them.
tell them you dont
tell him/her that you dont mean to break the ice but i kinda like you and please dont tell anyone, if he is a person who spreads rumors just dont tell the person

i really dont know so someone tell me
be honest if they like you like that tell them I think it's better we remain friends
Hey ......... I just wanted to tell you that I like you. If you dont like me then im cool with that but i really like you
Get with that person and dont tell anyone.
Just say '' Hey I like you whether you like it or not."
Tell them to seglum.
simply tell them how you feel! when i find out someone likes me and i like them back, i get super excited! if you like them back, tell them. and if you dont' break it to tem nicely :)
