Which characters exchange these lines and in what order in Act I Scene 1 of A Midsummer Night's Dream I frown up him yet he loves me still o that your frowns would teach my smiles such skill?

These lines are exchanged by Hermia and Helena, two friends. They are speaking of the young man Demetrius, who is in love with Hermia. Hermia, however, is in love with Lysander, and, to make matters more complicated, Helena loves Demetrius.

Hermia speaks first, commenting on how she cannot seem to shake Demetrius from his puppy love, even though she scorns him. Helena responds, saddened that even when she tries her hardest, she cannot gain Demetrius's affections.

In the end of the play, all is right--Lysander and Hermia are together, as are Demetrius and Helena.
