To be honest, they're mostly "Ouch."
"I Forgot How Much This Hurt."
Similar Thoughts: "This seems like it hurts more than the last time. Did I somehow get weaker?" "Did it always feel like this? Is something wrong with me?" "I wonder if this tattoo artist has a heavier hand than the others I've been to." "Maybe this is just a bad spot or I'm just being a wimp." "How far in is that needle going?"
"At Least the Liner is the Worst Part, Right?"
Similar Thoughts: "It'll get better once I get used to it, hopefully." "It's such a sharp stabbing pain... I feel it in my bones." "Is there going to be numbing cream at some point? You better not wipe me with a dry paper towel" "I hope the shading is easier, because this sucks so far."
"We Must Be Getting Close to Done."
Similar Thoughts: "How long have I been here? Is it still the same day?" "What do you mean we're almost done with the outline?" "There can't be too much left, it wasn't that big of a tattoo and there wasn't that much detail." "I don't remember the stencil going that far down... Are we sure it's still in the right place?"
