Give three reasons why cherry and marcia are not scared of johnny and ponyboy even though, like dally, they are greasers?

1) Cherry and Marcia knew that Ponyboy and Johnny were Greasers, however, they didn´t saw them as a danger at any moment, for their external looks, they still had a ¨inocence¨ and not threatening aura, so the girls didn´t feel uncomfortable with the meeting.

2) Cherry and Marcia felt the chemistry between her and the two guys and liked them, so definitely this aspect had an important impact on the first interaction between them.

3) The physical looks of Ponyboy and Johnny, if they weren´t attractive the history would be different (more at the end of that part, where the guys join the girls for a walk back home) so this as the first impression generated confidence and interest in the girls.
