Very difficult:

• Specificity

Downright impossible:

• Nope, no more booze for me.
• Sorry, but you're not really my type.
• No kebab for me, thank you.
• Good evening officer, isn't it lovely out tonight?
• I'm not interested in fighting you.
• Oh, I just couldn't - no one wants to hear me sing.
• No, I won't make any attempt to dance thanks, I have zero co-ordination.
