"I did have a dog for a few years when I was little, but then just really had cats until I was about 21"

This quote by Eric Roberts speaks to the concept of change and how our lives can be dramatically various from one period to the next. It suggests that when he was a child, he had a canine, however then his life changed and he had cats until he was 21. This might be analyzed as a metaphor for how life can be unpredictable and ever-changing. It might also be viewed as a tip that we ought to be open to new experiences and accept modification, even if it suggests leaving something we are familiar with behind. It is a tip that life has lots of surprises which we ought to be prepared to adapt to whatever comes our method.
