When I look back upon those days, it all seems like a dream. ✬

Look back! ✬

Don't look back. ✬

I sometimes look back on my childhood. ✬

When I look back on my life, I realize how much time I wasted. ✬

Tom did not look back. ✬

Never look back. ✬

Look back. ✬

Tom didn't look back. ✬

Look back there. ✬
