Thanks so much for your help dad! I had trouble getting it in but managed to complete the job... so tell mom not to worry you're not going to have to pop round and fix it haha.
And now you know how to repair or replace all door handles, if any get loose or if you need to rekey a door!!
I think my favorite part of learning to fix stuff is feeling that much more confident about the world around me, even if it's a small thing like knowing how to install a door handle.
Here's to you bettering yourself. :)
You can move mountains if you do things one step at a time. You can do great, big things!
