Back up your answer
Can you tell us more about why you think this is a good idea? Answers on Interpersonal Skills SE need to be well-justified and backed up with either evidence or personal experience that shows the OP that this is a good idea. See [this meta post](https://interpersonal.meta.stackexchange.com/q/3583) for more information.
Arwen Undómiel variation, about "try this" answers:
Hey, thanks for the answer! Can you please explain why you think that this is a good idea? Why do you say to take this course of action? What’s the thought process behind this answer? As this currently stands, this reads like "Try this!", which misses out information that helps the OP decide on a course of action. Answers here [should provide](https://interpersonal.meta.stackexchange.com/q/2003/) some sort of explanation for why they are suggesting this solution, which at the moment this answer doesn't appear to do.
Version 2, explicitly about backup:
Hey, thanks for the answer! Can you please explain why you think that this is a good idea? Answers here [should provide](https://interpersonal.meta.stackexchange.com/q/2003/) some sort of backup, such as personal experience or an external source, for why they are suggesting this solution, which at the moment this answer doesn't appear to do.
A "crash course" for new users:
Hi and welcome to IPS! Please take a minute to read our [citation expectations](https://interpersonal.meta.stackexchange.com/questions/3583). Answers on IPS need to include some backup in the form of either personal experience or references - could you explain why you think this advice will work, have you used this approach in a similar situation before, or is this something you've seen recommended by someone else? You might find [How do I write a good answer?](https://interpersonal.meta.stackexchange.com/q/3266/) helpful too.
(Consider editing the second-to-last sentence based on the particular answer - for instance, to highlight a particular aspect that you feel is on shaky ground, or to encourage the user to expand on some experience or reference that they hinted at in their answer.)
AElis variation to require back up from personal experience:
Hey! We [require](https://interpersonal.meta.stackexchange.com/a/3271) answers here to be backed up by personal experience or external sources. So, could you  to tell us about a similar situation you were in the past? Who was involved, what did you say and how did the other person react?
