Yeah, my friend who had it done looks very normal in normal conversation. The tongue can still act like a normal tongue, it's a slit, not constantly spread apart(unless you do the ridiculous way where you basically cut out a huge triangle out of your tongue, OUCH!)
When talking it seems fairly normal, maybe a bit like an odd looking tongue(but who looks at tongues when you're talking anyway? XD) and only when she sticks her tongue out and wiggles it could you really see it, lol!
But yeah, it's always good to research and wait..and research while you wait..and talk with people..etc.
I've been planning on getting a tattoo for about four years now and I know it still won't be for another several years before I get mine done. I know I want to be in a certain point in my life first(though they would be hidden, not like on my face or lower arms and hands lol), partially because it is an EXPENSIVE investment. Also as an artist I know how much I would not like to have a piece of art on my body that I later think is badly drawn! I want to have the ability to be flexible on price so I can afford to get the artist I respect enough and not just get what I can afford! I actually want to get a master copy tattoo. Basically a rework of a great artist's piece. I've always been drawn to Alphonse Mucha, he brought me into the art world and through his designs and inspiration I have made a lot of life changing decisions. I'd love to have a representative of his piece "summer".. But I don't want a dinky little 'almost looks like it' type thing.. Gotta be awesome and beautiful and the edges will be redesigned to suit a tattoo format better. Not to mention I want a tattoo representing my grandfather, Bear. It's a long story, but we were very close and went through a lot of family stuff together. When I was born he called me "baby lamb" and those were the names we went by together. I want to get a simple, but beautiful piece of a bear and a lamb. Not many people are super good at animals though, so I know who I want to get it done by already. And I'd love my one simple tattoo to be my artistic symbol I use as my 'trademark' for my art :) just simple, sweet, special. But of course, I'm still thinking about all of these things. I am considering how they would look if I chose to get new ones in the future and preparing for that possibility in regards of size and placement... Also considering price and size--I know small ones are cheaper, but if you want it super detailed, consider going a bit larger(so it isn't 'fuzzy).... Considering style, elegance, class, and of course what others will say(even though they are becoming much more mainstream and common now. Less 'trashy', especially since real artists have shown up in the tattoo world and shown tats can be more than skulls, chicks, and barbed wire) ..Been talking to the boy about it as well, and we've decided to wait at least until we're married before we get any tats. He wants a few as well, also tasteful and not out in the open..
But yeah :D
