It greatly depends on how well you know someone. If my husband were to lie to me, I would pick it up in a second. If I walked up to a group of people and they all got very quiet, and then one left, I would know they were talking either about me, or about something they did not want me to know. The main thing is to observe them, and do it more than once.
Sometimes an odd hesitation only means you're not quite sure about how to describe what you are looking at. Everyone isn't poetic. It could also be normal in this situation to have vocal change or a change in speech rate if you knew more about a particular bud, or if you found a flower you loved. Don't judge on a few minutes of something so simple. You will become distrustful.
