I could not give the seminar

As you all know I have planned to give a seminar about insurance to my students. The sad thing is I could not give the seminar during the scheduled date due to family issues. I have worked hard for the seminar but I could not share it with my students on Sunday. My students will understand my situation and I am sure that they will assemble in the conference hall this weekend. A week will not make a big change and my students will grasp everything I share with them.
