Let people help you. Refusing every offer takes away their chance to be the kind of person they want to be.

Accepting help is often framed as weakness, so it gets refused on reflex. What that misses is that helping is not a cost to the other person; it is something they wanted to do, and turning it down repeatedly removes their part in the friendship. Constant self-sufficiency can hold people at a distance while looking like consideration.

Say yes to the next offer, even a small one, even if you could manage alone. Let them do it their way without correcting the method. And when you need something, ask one person for one specific thing, which is much easier to say yes to.
