Instructors need to remember that everyone has a personal life that can and will take priority over what class they are taking. As professionals, we can often learn to put aside our problems and fall into the subject we are delivering. Students are not trianed or do not have the experience to do this and they allow their personal lives to run over their school lives. We must accept this as normal, work with them to some degree to try to help them, and, most importantly, accept the fact that sometimes we just cannot make the world better for all and make due with what we have to work with for the day.
