I (took) my seat and (decided) to pass the time watching the people around me.

It (was) hard to understand what he (was looking) at; from time to time he (threw) the magazine on the table and (picked up) another. Opposite me there (was) a young mother who (was trying) hard to quiet her son. The boy (made) aeroplane noises as he (was moving) an ashtray on the floor. Near him an old man (was sleeping) and the boy's mother (was) afraid that sooner or later her son (would wake) him up. I myself (was) sleepy. The boy (was) quiet now in his mother's arms. There (was) a deathly silence in the room and just at this moment the loud speaker (called) out the name of the next lucky person.
