Why are you so adamant that it has to be on your wrist? There are loads of easier places to cover up? I spent ages trying to decide where to get my tattoo and eventually decided on the back of my neck just above the neckline of most of tops. I can show it off if I want but if I don't want it to be seen its just as easy to cover with a collar. My mum was very against me getting it but I did it anyway and when she saw it she wasn't happy but she'll get over it and it's not her decision. My work isn't too fussed about tattoos but i'd still never choose to get any on my forearms, wrists, hands or any places that I can't cover.
