Can men and women just be friends?

Yes, but from a male perspective, it's his loss.

Women benefit more if they are just friends.

Women can use a male friend to carry stuff, protect her and have a shoulder to carry on.

Female friends are not helpful in giving men advice, of any kind, including how to pick up other women.

In the end, it just appear men only become friends with females hoping they could get more than just friendship. Have you ever had a female that you like and she won't sleep with you, but she sleeps with other men she just meets? 

Could I be wrong???
