Well, now I know. Dopey me to assume that "decent point" meant that you thought it was a decent point.
A decent point can mean lots of things, but it rarely means to agree.
A decent point is when one extends the index finger and indicates his preference for things affixed on the horizon of the aftermath of the happening. Immeasurably, it can be a good point for a good view, or a bad view with a good point, as pointed out before. Thus, it can be pointed out that pointing out the good point is sometimes pointless, especially if it is a bad view or the views are bad, particularly if the person cannot make a point having no index finger. The person that cannot make a decent point, thus has to have a substitute method, often consisting of a middle finger, which is more than apt for some to make a point, but terribly inadequate to get a nice view.
