I had a key made that said "truth" on it. Honesty has always been incredibly important to me. When I was younger, I was catty and manipulative. I wouldn't always say the nicest things about people and I needed to work on that.
The past few years have taught me how important honesty is with everyone - including yourself. I knew someone who hurt a lot of people (especially me), but more than anyone, himself. I loved him, and still do, no matter how much he hurt me. I gave him the key and he knew how much it meant to me. I'm not sure if he still has it, but I like to think it made an impact. I now have the word truth tattooed on my side. I may have given the key away, but the word and its importance will stay with me forever.
