Between good, smart or irresponsible.

Is a boy who does not give any problem at home,good and is a student who scores straight As in examination, bright? A retired man worries over the safety of his son on convocation day. He has asked the latter to collect a car sticker from the administration building. The son however, did not come back even after a one and a half hour wait. He could not find him anywhere in the college hall where the convocation was held and on asking around found out that the son had actually stopped turning up for classes after the first semester. Maybe, some people are just irresponsible.
