Sure it's normal for people to make an assessment on other people. Some of those people fall outside the bell curve.
The middle of the bell curve for a particular trait (e.g. talking on the telephone) is normal - so about 90% of the population.
You want to redefine the word normal. OK, sure. What should I use? Different? Strange? Unique? Flower? Snowflake? I don't know. Sounds pretty odd behaviour to me. Not wrong, not bad, not dirty. Just weird. Odd. Not normal.
Have you done/read any studies on people's telephone behaviour? No? Then how can you speculate about what does and doesn't fall within 2 standard deviations of the mean?
