Eh. He's an old man. My grandpa is the same and my grandpa is in no way creepy. Just affectionate.

This awkward encounter is explained away easily because she's a young family friend, he's telling her she can leave and not have to pose for all these photos soon which is why she's smiling uncomfortably. She's uncomfortable with the situation, not the man who is whispering to her who she has known for years, since she's the daughter of one of his friends.

People like you are the creepy ones when you're actively looking for signs that people are doing something wrong, to the point where you're convinced he's a creepy old man from one video where he's whispering to a child who is surrounded by photographers and politicians. But hey, it's Defs only her dad's friend biden that's causing discomfort. Shed be totally at ease if he wasn't there right ?
