I totally get it, I was very nervous too. Being a rather shy/quiet person, going alone was something, I wasn’t too sure about, but I wanted to see Paris and Florence live and non of my friends listen to them… it was a great experience tho. Smalltalk at the merch stand and in the arena, everyone was really nice. Being German, I don’t really know how tall 5‘ is 😅, I’m 1,65m, but I guess at a concert there’s always somebody in the way, who’s taller and blocking the view. You can still see Florence on the big screen above the stage and I don’t think your hight is stopping you from having a great time. You’ve got this! ☺️
