My experience in my circle of people I see with nails decorated with art, are normally the ones with either little spare money each month (and I hear / see their struggles) and/or ones that are always busy and don’t have time for meeting friends / family etc but can get their nails done fortnightly.
Aah right, I see. Yes. So they're either poor, and should therefore be not have their nails done because you don't value it. Or they don't make time for you. Maybe it's because you come across as really judgemental?
In my experience Raymond if a nail tech takes two and a half hours, the customer is either having a really elaborate set of nails, or she's a new nail tech who is learning. I've been having my nails done for 15+ years. It's never taken 2.5 hours, ever.
I appreciate a nice set of manicured nails and a polished look could make people feel better (as would someone highlighting their hair). But the glitter, gems, piercings and different colours looks OTT. It comes across as “look at me”.
Why should they not want people to look at them? What's wrong with being looked at? Your very long hair probably makes people look at you, or are they looking at you differently because your very long hair isn't what you consider to be a negative or OTT?
