Striking up a conversation with a complete stranger can sometimes be a risk as you don't want to find yourself awkwardly trapped in a dead-end chat with a seemingly crazy person. Still, we all probably have at least one memory of a short interaction with someone we've never seen again that we look back on fondly. A funny comment from someone at a store that brightened up a horrible day, a waiter in a place you've never visited again who went above and beyond on an otherwise terrible evening, or someone who made the effort to lend a hand when you needed help strictly out of kindness can definitely stand out. Even if you know at the time you'll never run into that person again, a few minutes or some quick words of wisdom can mean a whole lot in hindsight.
