Many are opportunists. They are surrounded by guys with some being real suckers who will do anything to please a girl in the hope she will like him. They will ask for expensive presents knowing well they will get them. This is because some guys either have lots of money to throw around and probably have many girls that they 'support' but get rewards in return from the girls. On the other hand, there are the suckers looking for love but these girls will use them and move on with their expensive presents.
