Günter Grass on the limitation of verbs

"I discovered that the verb tenses taught in grammar school—past, present, and future—are not so simple in real life. Every time I think about the future, my knowledge of the past and the present are there, affecting what I call future. And sentences that were said yesterday may not really be past and done with—perhaps they will have a future. Mentally, we are not restricted to chronology—we are aware of many different times at once, as if they were one. ”
