Mexanese Mumbo Jumbo

My grandma is 93 yrs old. She's a current resident at Carlton Gardens due to old age and slight dimensia. I went to visit her one weekend and was greeted by my grandpa. After saying Hi to my grandma and listening to her mention how she used to have long black hair like me - the usual routine - I sat and listened to Grandpa regail me of stories of their past. They once had a boat and they used to go sailing to Pender island all the time. They were both retired then so I suppose they had nothing better to do with their time. I have vague memories of standing on the docks with a foot on the boat, probably too scared to actually step onto the boat - my sister is the fearless one in the family. The story continued as I listened quietly and asked questions only when there was complete silence otherwise Grandpa would continue along having not heard me. Randomly when my grandma thought we were talking about her, she would try contributing to the convo but it generally was a mumble combination of japanese and "aaahhhh". Finally after about an hour, I started to get ready to go. The moment I stood up, my grandma reached for her walking cane, slowly got up and headed to the door. Slightly startled, and frankly shocked at the speed my grandma moved past me, I quickly said goodbye to Grandpa and rushed after Grandma. Luckily for me her charm school training stopped her at the door and she paused to say " It was nice to meet you " before she sped off down the hallway, unsure of where she was going, just knowing it was time to go.
