"Has Grandpa finally lost it?" Yang Qing wondered out loud, as he saw the dust storm he left behind.
"He has always lost it.." said his father with his brother nodding along in agreement which drew a strange look from Yang Qing who as far as he saw it, his brother was slowly following their grandfather's footsteps. He felt it wasn't long now. He could see that crazy experimental fanaticism flame slowly growing in his brother's eyes. He wasn't sure if the person in question had noticed it yet.
