This is from a book called Works Well With Others: An Outsider’s Guide to Shaking Hands, Shutting Up, Handling Jerks, and Other Crucial Skills in Business That No One Ever Teaches You by Ross McCammon.
If you're not sure how you feel about someone, ask yourself two questions: would I have two beers with this person (aka: are they fun?) and would I let this person take care of my puppy for a weekend (are they responsible?). The answer could be no and no, yes and no, no and yes, or yes and yes.
And now you know, if this is a person to avoid, a person to have fun with but not trust with a lot of responsibility, a person who's not very fun but trustworthy, or someone you like to hang with AND trust.
Honestly, in most cases I don't think doing the "two beers and a puppy" test on someone will lead to a revelation or surprise, but it's a fun way to be more explicit with yourself about your feelings.
