Hair coloring

I had been saying to my friend that I’m going to dye my hair in mint colour for a year while she planned to dye in peach colour. I was planning to visit the hairdresser next week. But today she sends me the photo where she dyed her hair exactly in mint (but before she preferred peach) and said that she. just. forgot. the thing. which I had been saying for a year. I don’t know should I be mad…
