This is not about a specific person but rather the state of being a grump, grumps usually don’t like to hang out with other people, tend to keep tothemselves both physically and emotionally, which is fine but when it starts to cut people in your life that’s when you should reconsider your grump state. A grump role is usually taken up by an elder or grandparent but cannot and does not conform to typical standards of glee.
Remember this is not about a you!
