I worked with someone many years ago and her son had done really well and got selected to go to a sports academy for a sport he loved. Someone at work asked if he was excited etc. He had been awake crying every night since he found out about it. When his mum asked him what was wrong and why he was so upset he said I am worrying about what will happen if someone asks my name. Then he started crying again saying but the big boys will all laugh and make fun of it because everybody else does. This happened over 40 years ago and its as vivid as ever.
So sad - that's the reality of giving kids ridiculous names. People will say how nasty we are on MN for making fun of absurd name choices (not just slightly unusual ones); but it's far better to present your planned name to MN and then get upset for an evening as your dream name is torn to shreds, before swapping it for a much more sensible choice as a result, than it is to go ahead in blissful ignorance and call your baby something that will ensure them a lifetime of mockery and force them to avoid telling people their own name.
What's worse is that the child will suffer the mockery and not the parent, after the first couple of years of their life. I have no doubt that there are loads of kids out there with utterly stupid names whose parents will blithely say "Oh, she loves having a non-boring name!" whilst their child is not only very much not loving it at all, but is also trying to shield their permanent upset from their parents, out of a desire not to upset them.
I know it's become a MN cliche, but if only more parents would test out a wacky name in advance and introduce themselves as that name to strangers, to see how well it's received - not just mockery, necessarily, but maybe endless confusion as to pronunciation or spelling. What possible single positive could come to a person's life from being called 'Jaiymz' rather than James? Or even being called James, if it's a girl?
As a general rule, if you as a 35yo adult are then hesitant about telling people 'your' name and find yourself holding back, imagine what it's like for a young child without the same life experience, thick skin or confidence.
