I hate my hats...

Am torn between two matters at the moment. Without giving too much detail, I was invited to give a talk at a dinner of my former Alma mater for the graduating batch....the problem is I have taken leave....we are suppose to go back to Taiping for hubby's land matters. It would be very selfish of me to postpone the trip to another day but you don't get this sort of opportunity knocking on your doors all the time. HELP, should I be a good and reasonable wife OR be in a position to give some aspiration to some eager beavers....I hate my different hats at the moment.
