I think that's the perfect illustration of the paradox of fame.
Sometimes, you just want to be a "normal person" and be part of the group but then people come up to you all the time, because they only have a 5 minute conversation with you, so it seems like no big deal. However, you have 50 5 minute conversations about the same thing with each person and it gets tiring.
So people decide to respect your space and you stand there all alone. It has to be a bit weird.
