My granddad is so patronising?

he constantly says im just a child (im 16 not a child) and i have nothing to worry about because mummy sorts it all out, and he means it. but i have more to worry about than him.......getting a university place, rising universoty fees, the jobmarket, depleted resources, m immigration.......im living in a screwed up world an i have exams around the corner. i have it worse than him right? and im not a child right?
