I turned 49 & my younger daugh. & I got tattoos, my older daugh. says I am too old 4 tattoos. What do u think?

My younger daughter is 23 and we have both wanted to get a tattoo for a few years so we just decided to go for it yesterday on my birthday. I got a cross inside a circle with swirly filigree around it on my ankle. She got a erfly on her shoulder. My older daughter doesn't say anything about hers, but she thinks I am too old to get one. What should I say to her?
