Don't Be That Guy
In my part-time job, I sell guns at a retail store. One thing I see occasionally is couples for whom one partner is more experienced with firearms than the other. This is usually but not always a female who is less experienced and a male who is more experienced. Sometimes, when I am showing the less experienced partner a firearm, the more experienced partner cannot resist injecting comments and advice, which can sometimes ruin the experience for the less experienced partner.
