You can make anything sound crazy when you put it like that, but yes, this is actually very good advice and comparison.

The rubber duck technique is a completely valid method of working your way through a problem. Sometimes you don't need someone to tell you how to resolve your issue, you just need a chance to talk it through before finding the solution yourself.

Choosing to let your friends/family/loved ones use you as their metaphorical rubber duck as a way of emotionally supporting them is a very common and expected way of communicating with others. A lot of people will do this with the expecation of you just being there to listen to them while they work through whatever their issue is.

Our task is to figure out if they need us to be the rubber duck, the outside perspective, or the man with a plan when they come to us with a problem.

My meme is actually a bit tongue-in-cheek, actually, specifically because of this. Proposing a solution to a problem that someone brings to you is only sometimes the way to continue, and often times it can be disastrous when they just wanted a rubber duck, or sympathetic ear instead.
