... Grandpa should know that we are different generations, so obviously this granddaughter would not have played nor will she like playing it.
I used to do that when I saw a kid using a computer, Me: let's see how well you control your mouse, try playing this game. xD
I'll laugh so hard if gramp meant an one of those actual maze at a fair or something, maybe on Halloween or something other holiday where it is reasonable for the event to last past midnight.
