Maybe it's because last month Malachai had a substitute teacher yell at him and tell him he had better come to school with combed hair the next day (or else! . . . ).
Or maybe it's because they heard that nicely combed hair helps prevent a lice epidemic.
Or maybe because all the other boys show up at the school gate with slickety-slick hairdos every morning.
they are very handsome with combed hair
(but I think that I might make a house rule that they are not allowed to comb their hair on weekends)
