Hey Mohamed, how are you? I hope you are doing just fine!
I shall provide you with an explanation of the meaning of the idiom ''strike (someone) as (something)''. Firstly, allow me to give you a piece of advice --> you should not confuse the verb ''consider'' with ''strike'' as they mean different things - the former is used to mean ''think or deem to be / to regard (someone) as (something)''; and the latter is rarely used in the sense of ''to impress someone as a particular type of person or to affect someone in a certain way...''
1) ''Strike someone as something'':
--> [for a thought or behaviour] to affect someone in a certain way.
E.g.: ''His rude behaviour struck me as surprising''.
E.g.: ''My sister's attitude struck me as childish.
--> [for a person] to impress someone as something or a particular type of person.
E.g.: ''You strike me as thoughtful''.
E.g.: ''You don't strike me as the type of person to do something like that''.
* May I provide you with additional information?
2) ''Strike'' is also used in the following ways to describe the effect something has on a person's mind:
--> If an idea or thought strikes you, it comes into your mind suddenly:
E.g.: ''It struck him how foolish his behaviour had been''.
E.g.: ''I may say it struck me the way Dad reacted before the judge''.
--> If something strikes you in a particular way, it gives you a particular impression.
E.g.: ''She strikes me as a very silly girl''.
E.g.: ''How did London strike you?''
--> If you are struck by something, you are very impressed with it.
E.g.: ''I was struck by his good manners''.
E.g.: ''All of us had been struck by his kindness when he supplied the poor with plenty of food''.
Hope that helps!!! :)
