it is the last cut on side two of the MONSTER album put out by the band steppenwolf, in 1970... the song was never listed on the album... great cut... i still have the album... i was the first album...
Well you could start by commenting on what you like In her then follow it up by telling her how you feel and that you are hoping that she feels the same way blah blah blah the usual
If it is outrageous and you know that you would never like them, you could joke around and agree with them. You could always just deny it also. If they don't give up though, I suggest just ignoring...
