The next line, mentions that the poet ‘heeded not the summons’ which may either refer to the fact that he did not listen or give attentions to the calling of his parents to return home, or that perhaps he ignored the fact that the sun was setting and the day was getting darker as a cue for him to be returning home. The reason suggested for this can be found in the noun phrase ‘happy time’: the poet does not want to return home and retire because he is having fun.
