自信难听话怎么说英语

To say "confident but difficult to talk to" in English, you can say "arrogant" or "conceited." These words describe someone who is confident in their own abilities, but who may be difficult to talk to because they have an overly high opinion of themselves. Alternatively, you could say "cocky" or "overconfident," which convey a similar meaning.
It's important to note that these words can have negative connotations and may not be viewed as complimentary. If you want to describe someone who is confident but not necessarily difficult to talk to, you could use the word "self-assured" or "self-confident."
