I just realized, spending time with my 117 year old Grandma requires the same brain power and physical exertion from me as when I am hanging out with my 4 year old.
For one, its in my best interest to always have a kleenex on hand.
And oddly enough, it seems that both my toddler and my grandma can be entertained by the same stories for a considerable period of time. The more obscure details the better. The more family references the better. The more bringing up the specific modes of transportation the better. Seriously. Think about it.
Sometimes they both need some assistance using the potty.
I often have to repeat myself 5 times before they hear me and acknowledge I have spoken.
Our time together usually ends with them needed a nap.
Disclaimer: I do not actually have a 117 year old grandma. But in respect for my elders and any old person that may exhibit these qualities that is related to me and is actually willing to spend time with me and my family, I think I shall keep it vague.
