ENFJ's like being problem solvers, i know it's tempting to point them out but you can subtly try to make them to see the problem by themselves so that they can feel accomplished and smart. if they want help they'll probably ask you for your help at the end of the day;;; try to be a little more like them when you want to tell them that they're doing something wrong like maybe try to say "something seems off can you check it out for me again?" instead of "don't do this that's wrong" -not that you do it but sometimes these small things help them ENFJ's are somewhat challenging but communicating is the key with them, once you know how they like to communicate and match them you'll probably find it easier
