One's first impression is likely to be that everyone is in a rush.

Very often I find Western people seem to go for the more cliché Chinese faces: long hair, slanted eyes.

If you do better next time, then people will often forget their first impression of you.

This teacher made a deep impression on me not because of his teaching but because of his strong personality.

Yet, as I say, I possess a memory which elevates my impression of the teachers there to an ideal plane.
