My guinea pig hates me, doesn't he?

I had an incident like that with my gerbils. He will warm up to you. You should put some treats in your hand and offer them to the guinea pig while he is inside of his cage, if that is possible. Also, leave him alone for a few days before you do this. Don't take him out for a while, just let him eat out of your hand. My gerbils did that the first day i got them, but now they love me and enjoy eating out of my hand and they let me inspect them for any signs of illness.
