It's in the Flash
I see a lot of posts on forums that I follow which state simple declarations like, “I never use flash if I can help it” or “I hate using flash”. I have never been in the camp who disregards flash as a viable tool to get the photo. In fact I feel that if used properly there can be a lot of fun to be had with flash.
But most modern cameras can attain such high ISO that it allows people to get the shot without flash, and I believe this is becoming “a thing”. If you have the time and the right setting, dust off that old flash unit and give it a try. If you play around with it long enough, you may see that you can find a look that makes you happy, and brings moments into a different light. Ok corny yes but you know what I mean.
