Need help with interpreting 2 poems, 'Where the sidewalk ends' and 'The road not taken'?

Question

http://famouspoetsandpoems.com/poets/shel_silverstein/poems/14836 is where the sidewalk ends.

http://famouspoetsandpoems.com/poets/robert_frost/poems/528 is the road not taken

I need help interpreting them, and finding their deeper meanings. If you have other helpful annotations about specifics parts of it, it would be greatly appreciated!!

Answer 1

where the sidewalk ends is about recapturing childhood (especially imagination) and thinking outside the box

the road not taken is about choices--ones that you can't take back
