He is a hardcore introvert for sure. He is definitely a man of few words. He likes his routine and follows it every day like clockwork. He always looks like he's thinking about really deep subjects that are so complex and otherworldly, nobody could possibly comprehend it. He doesn't express these thoughts to other people. He loves kids and mostly loves to just play. It's as if he's a little kid too! He gets so much joy out of it. I don't think I've ever seen him happier than when he is talking with his grandchildren. I think he is a practical person. He doesn't ask for anything from anybody or expect anything. The only time I've ever seen him show anger is when my cousins and I were little and we were playing with the toy train set under the Christmas tree. We accidentally derailed it and had to ask him to put it back on the track. He came into the room and swore up a storm, fixed it and then went back into the other room. But he was over it in 5 minutes and everything was back to normal again. We derailed that train a lot when we were kids and every time he had the same reaction. I still don't know why he'd get so mad about something like that. Oh and then lastly, my grandma is always talking his ear off and he looks like he's not listening but then he makes a passionate statement and you realize he was the whole time! My grandma is really active and drags him all over the place and he puts up with it all. They are so cute together!
