My personality came through when I was living the worldly part of my life. I became incredibly talkative, funny, and exciting to be around. At the meetings and on service, I was quiet, shy, and shared very little of my true personality with others.It just becomes natural. You subconsciously know who you can be yourself around, and who you have to tiptoe around.
That's pretty much it. I was the same way.
