strike (one) as (something)
To cause one to consider someone or something as being a certain type of person or thing. You don't strike me as the type to take criticism like that very lightly. The design just doesn't strike me as anything particularly unique or interesting.
strike someone as something
1. [for a thought or behavior] to affect someone a certain way. John's rude behavior struck me as surprising. Mary's attitude struck me as childish.
2. [for a person] to impress someone as something or a particular type of person. You strike me as thoughtful. You don't strike me as the type of person to do something like that.
