Really curious to know how you explain your job to your grandparents.
I will go first. My job is to tell a computer what to do. I am the king and my computer is my servant. He does exactly what I tell him to do. :)
Grandpa, I'm trying to produce something in this world of consumption madness. Sometimes this can be a scientific study, a product, or even just an article!
I help children with reading challenges read better using a machine that understands their individual difficulties very well. Although I have to say, I once asked my grandma what she thought of mobile phones and she was completely unfazed, she said "you know, there were no airplanes when I was a little girl. At my age, you've really seen it all" :D
