I don't know if you are a girl or not
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 :)
if you dont have feelings about him like if you dont want to date him ten ask him nicely if he can back off
Well tell the first person that you like him/her as a friend not as a GF/BF but nicely so you don't lose that person and tell the person that you like that you like him/her back and that will start the relasion ship.
Do NOT lead him on, or leave him hanging. Unfortuanetly you just have to tell him straight up. Nicely though, you dont want to hurt his feelings.
Tell Them ...... If they dont like you back they lost out on a great person, and you move on.
Move on from that person and get with someone else and show them how much better you can do without them!!
tell her off nicely
tell him/her you dont like that person
you tell them there a really nice guy but you dont really like them
you have to try as best as you can to go off them eg dont look at them constantly dont talk as much and eventually you ewill find the right person that suits you
Nicely say your not at all interesed and you want to be friends.
just tell her that you dont really like her in the way she likes you nicely or you will hurt her feelings.
