Reflection for Sonnet 2

This sonnet is somewhat carpe diem. The speaker is telling the young man that he is going to be old before he knows it, and that in his old age he might regret not having any children to carry on the line. The speaker is telling the young man to seize the day now while he can before he gets old and loses his beauty. He will have something to show for himself when he has nothing. The speaker makes a quick transition from saying "thy beauty" to calling the young man a "tottered weed" only two lines later. This may have been done to make it seem more dramatic, like how quickly his looks may fade once he becomes old. The last line may be a reference to how his child's blood will be warm when his is cold from death, and it could also mean that his blood line will be warm when he is dead.
