@lordrootman "...we can simply takes their words for it".
While this might occur for those less familiar, most of the more practiced folks here will ask a few mindful questions to try and help steer someone in a proper direction.

There are other factors to consider, hence the more detailed follow-up questions by some folks here just trying to help. That's all.
