I'm glad you managed to own it, but not everybody has the confidence to do so.
To be hyperbolic, suppose that your 3yo older sibling had been given complete free rein to choose a name for you, with the result that your official lifelong name (or at least until you were old enough to change it) was 'Poopypants'. Now, you might be the world's biggest extrovert and exploit it - get in there first ("Yes, I know it's a crap name!!!!") and figure that it was at least distinctive and nobody would ever forget it; but if you were a very introverted person - a child starting at school at one point - and you had to tell everybody your name, then assuring them that it was your actual name when they laughed (the other children) or told you not to be rude/silly (the adults). How do you think most people would feel at that?
Now I know that 'Garri' isn't as extreme as that, but how do you think a maybe shy, timid, introverted, lacking-in-confidence and/or self-conscious girl who had to constantly introduce herself with a name that is only really known as a boys' name - indeed one that isn't really used for boys anymore, so virtually all of the other people called (what sounds like) that exact name are male and over 40 - would feel every single time she met a new person?
Incidentally, how come you were named after your Dad? Did you not have a Mum, or another female relative, if they were determined not to give you your own individual name?
