Baffled By A Smart Email

Its late, i know - yes yes ill go to bed soon.
Just recieved an email in response to my thesis work.
Its a very smart response from one of Intels design anthropologists:

If you are using an questionnaire, then are you really doing
anthropology?
:-)
Sure send away.

Short interview is also fine depending on what time zone you are in and
what constitutes "short".

I feel almost a bit embaressed. That I suggested a questionnaire when I know that in anthropology it equals to short sightedness - no texture, colour or context driven quality will be gathered from such a data-devoid method.
A short interview, is also suspiscious - its becomes constrained, which means 'aimed' or 'focus targeted'.

I should be happy he answered at all.
