If someone asked me whether I find something interesting, and I did not want to show negative feeling and wanted to hold my tongue, what conversational English should I use?:
-No feeling.
-I am neutral.
-So so.
You would not be speaking, period, and you would show no feelings after someone asked you the given question. That is what I've gathered. But secretly you had some type of feelings because you say you wanted to hold your tongue. Holding your tongue would be you being quiet, saying nothing.
