You could spend your whole life trying not to offend people. I think that we often times think that people are much more critical of us than they really are. I think the true Alice fans who notice it will appreciate it... those who don't, I wouldn't worry about it. If it bothers someone they will forget about it 2 minute later and move on with their day.
I have Alice in wonderland tattoos that I got as a naive 18 year old, one wrist has a drink me bottle and the other wrist has the eat me cookie. As you can imagine seeing one wrist and not the other looks…. Bad….should I cover it up while at the parks?
