Quite so. Imagine agreeing to do any other activity together with someone else, and then immediately separating yourself from them because you decide that is more efficient. Agree to, say, cook a meal with someone -- but you decide to just prepare your own portion, and then go do something else while they are still trying to figure out how to chop some unusual vegetable. Is that person ever going to want to cook a meal with you again? I suspect not, and you can't force them to. Instead, show them how to chop that vegetable, maybe discuss general technique, maybe even divide labor in a more reasonable way -- whatever works best for the two of you. It will probably take you longer, but you'll probably also get to do the collaborative activity again.
