He doesn't seem to have the time to give the proper answers to many questions.
In one month somebody asked him if he liked classical music and he replied saying what his favourite piece by Mozart was.
However, when I asked him the same question this month he responded simply by saying he knew nothing about music.
It seems he's just putting in the first thing that comes into his head in order to save time.
Still, in these modern times we're all a bit rushed I suppose.
