Avatar/signature vs. true personality?

Haven't had anyone mention anything about my avatar or username for that matter. When I signed up I couldn't think of anything related to me and/or my car right off but finally came up with Fishy68. Started to go with "somethingsFishy" but thought it sounded too long but after seeing some usernames on here now it wouldn't be out of place. J Par it sounds like we're in the same age group cause I'm 53
