Go in the bag

It happened that the basketball coach chose our colleague Omar to be one of the members of the school team, but that did not sit well with Qais and Hatim, because Omar is shorter in height than the other children in the class. Therefore, they no longer consider him important among their classmates, nor do they show him respect during play. One time, Omar found his sports clothes wet with water inside his bag, so he did not participate in that day's match, and instead, a player from the reserve team played in his place. The next day, Omar withdrew from the basketball team, claiming that his time does not allow him to commit to any sports activity.
