I had this issue. You can do what home builders do when they pour concrete driveways. They "sleeve" under the slab of concrete.
You however will have to do it after the fact. Go to a home improvement store and buy a 3-4 inch PVC pipe and caps (no PVC glue). Dig down on both sides of the walkway about 6-8 inches and saturate the dirt with water.
Cap both ends of the PVC pipe and use a rubber mallet to pound the PVC pipe under the walkway. Remove the caps. At the end you will be able to simply push any drip line through the open PVC pipe and route it where you need.
Hope this helps.
Depending how long the walk way is we have gone around to the other side or we have gone under the brick to get to the other side.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
