Do you think I should slap my aunt back after she slapped me?
Why did she slap you in the first place?
She was upset with something I said and she took it out of context.
I don't think you should hit her back, you might hurt her. Tell her how you feel and that it upsets you to be slapped. Revenge never works.
I'm not sure that she'll understand how I feel, she gets so angry sometimes.
I'm sure it's frustrating for you to deal with your aunt, but slapping her back will make her very upset. Try to talk to her about how her actions make you feel and be patient with her.
