Professional was just an EXAMPLE!! say you have two female graduates...going for their first 'big' job, in whatever area they qualified in. One has a regular name, call her what you will. Let's just call her Laura someone. Then you have the other girl, who has some wacky 'fashionable' name. Something weird like Crystalyn or KittyJayne (yes, I know of a person that had this stupid name).
In professional work, having a crazy name doesn't look good.
Hmm my first name is Crystal and my middle name is Lynne. I am pretty sure if I was to suddenly start going by Crystal Lynne it would not cause me any problems.
Kitty? Hmm my Aunt went by the name Kitty for years before her passing (spin off on her childhood nickname-Kitten) nobody failed to take her serious.
We had names picked out long before our son was born. Hunter for a boy and Jade for a girl.
We got a boy his name is Hunter (Devin is his middle name) Were we to have a girl down the line she would more than likely be Jade..not sure what the middle name would be yet.
Were we to have another boy down the line I love the name Tristan.
Incidentally I looked up what Labra means. It is the plural of Labrum:
La·brum (lbrm)
n. pl. la·bra (-br)
1. A lip or liplike structure, such as the one forming the roof of the mouth in insects.
2. The outer margin of the opening of a gastropod shell.
No reason in mentioning that aside from I find it interesting that you are critiquing name choices when one looks into what your choice of (screen)name means.
