Sprained wrist

I was mending the pipe. It's leaking.

The pipe is a HDPE pipe. The black one.

The advantages of using one are, it's durability, there no need to apply glue and it's more flexible than copper or PVC.

However, there a downside that I dislike. One must be careful when connecting HDPE pipes. One must insert the compression nuts and then the white thingy and then the O-ring.

I did all correctly, but I force the white thing into one of the pipe. And I sprained my wrist. My left wrist, my dominant hand.

It's painful and I have tons of assignment.

And my tyre failed too. I can't change the tyre even with good hands, what more to say with a sprained wrist. Why the car manufacturer produce tight rims and wheel hubs...
