Of course I am senior to you, junior, but then you are probably senior to your younger siblings (if any). It's not a particularly useful term and I dislike it because I dislike being pigeon-holed. Yes, I too have (mostly) silver hair. If I were a blonde, I would dislike being categorised because of the connotations that word has accumulated over the years (bimbo... airhead...). If you can't pigeon-hole me by my age or the colour of my hair, what then? Does it matter. We are as diverse as any other group... and so is your generation which one day will be, dare I say it, 'senior'.
