If I were you, I wouldn’t be too worried about this. Have you thought this guy is a bad influence for your friend?
Obviously, If I were you I would talk to your friend as quickly as possible. You must give advice, because if Steve is a bad guy, he can hurt the feelings of your friend, and he can injure her.
Ask for the boy, and how does she feel when she’s with Steve. Maybe she’s scared of Steve. I don’t know. You should talk to her.
Mam nadzieję, że pomogłem xD
