<human>: Can you summarize the given text in a few sentences?

My girlfriend is very attached to me (see previous posts). But sometimes I don't want to do certain things, though I usually take her places she needs to go.

She is getting her hair dyed. She has never done it before. She told me she wants to postpone going now because she doesn't want to go alone. She says "it's a big change." This is coming from the girl who got a large tattoo without even telling me until the next day.

I really don't want to go sit in a salon for over an hour. Ladies help me out. How long will it take to bleach and dye thick hair that is lower-back length? She also needs the ends cleaned up a bit. Whatever it is, I don't want to sit there awkwardly and wait. She's getting it done by her old friend who I assume she's going to catch up with. 

I'm pretty sure I'm not being mean in not wanting to go. I don't want an argument so I want to say the right words if she brings it up again. Is it okay to say "Girlfriend, I don't want to sit alone in a salon for over an hour while you get your hair dyed."? If she says something about the big change is it wrong to bring up her tattoo?

I understand this makes me sound spineless, but I'm really tired this week and I just want this to go as painlessly as possible. Thank you for reading my extremely insignificant issue.
<bot>: Don't want to watch my girlfriend dye her hair. Want to know the most painless way to tell her no.
