It is essential to my T and having worked with others that did not share that value I can tell you it is a whole different world. Yes, it still sucks some times, it still hurts but there is healing and comfort.
As a kid my mom cleaned cuts with alcohol. My dad cleaned them with saline and soap. Either way they never got infected but I went to dad when I got a cut or scrape and hid them from mom... the hidden ones sometimes got infected.
