Twitter has become the high tech way for your favorite stars to give you a peek into their lives, and David Nail is no exception!   The "Let it Rain" singer tweeted about something that happened to him last week outside a Kroger store.   “Two young girls begin following me from aisle to aisle! I smile a few times, even see em behind me as I check out!”  he wrote.    He goes on to say as he was getting to his car, one of them asks if her friend can sing for him.   "I said, honey if you’re willing to sing in broad daylight In a Kroger parking lot, you’ve already impressed me!"   David let them take pictures with him and wished the 12 year olds the best of luck, "One of the sweetest moments I've ever shared out in public with fans! Made my day! I have no doubt she would've sounded great with courage like that!”     Definitely, an "awwww" moment!  While David didn't let the young lady actually audition, no doubt he made her day!!!
