each time davids dad answered , and david heard him reassure either mr. or mrs. skievaski that , yes we were still going , that no , he didnt think the slight threat of showers early this evening would cancel the game , that yes , it would be a good idea for shelton to wear a hat , but that since the temperatures were likely to be in the 90 's , and we would be home before dark , a jacket was not necessary , and no , there was food served at the stadium , so it was not necessary for mrs. skievaski to pack a basket , and finally that no , a tie was definitely not necessary .
