Mingling means I talk with other people in a party or make friends with them,or in some other situations, (this is correct, to mingle is to mix and talk with many people) for example, a boy is mingling with his girlfriend in a relationship,am I right? (This is not really correct, the boy is not mingling, meaning talking with many different people, he is only with his girlfriend, mingling would not be used here) Is the following sentence right or not:the girl is reserved and sensitive,it's hard to mingle.? (The idea is correct, the grammar a little off, "The girl is reserved and sensitive, it's hard for her to mingle." This sounds better)
