I have no definite answer. It could potentially draw elements from real life, or it could be completely made up. Maybe you could check reliable sources or reviews to find out more.
One challenge is having the right materials. For example, if mending a clothesline, you need the same type of rope or wire. Another is the skill. If it's a complex line like an electrical one, you need trained technicians. Also, time can be a challenge. If it's a fence line that needs mending to keep animals in, you can't take too long.
I'm not sure. It depends on various factors like the source and the author's intention. Sometimes stories are inspired by real events but have fictional elements added.
Well, in a true story I know, mending the line was about fixing a fence line. The old wooden fence had some broken parts due to a storm. We had to gather new wood, measure the right lengths, and carefully replace the damaged pieces. It was a time - consuming but necessary task to keep the property enclosed and safe.
