Showing offence

When someone says something to you which is rude, they are being offensive; you are offended (you are shocked and angry). When we take offence to what someone has said we use the following phrases to let the person know that we are not happy with what they said:

• You can't talk to me like that!
• I'm sorry, but I'm not going to let you talk to me like that!
• Don't talk to me like that!
• I take offence at what you just said!
• Don't be so offensive / That's offensive!
• Take back what you just said! / Take that back!

Note: Offence is British English spelling; offense is American English.
