People like that don’t seem to get it. Went through that. You may have to just show it in your actions with them. Avoid headaches at all costs. That’s annoying.
‘I know how much you love to… while I know you want to help, I feel better doing this on my own.’ Boundaries are about holding it. Every time they go to do the thing, step in indicating you’ve got it. Boundary: what you can do Request: asking them to do something
I'd tell them that I appreciate the effort and their want to help however I want to [do / experience with such task] I will keep you in mind when I want your help for [ what ever you're comfortable with].
