'Harry Potter' star Emma Watson says her introvert and shy nature compels her to remain quiet at the parties.
The 23-year-old actress feels nervous at the parties as she finds it difficult to indulge in small talks, reported Daily Mirror.
"I feel like I've been given a lot of credit where it isn't due that I don't like to party. The truth is that I'm genuinely a shy, socially awkward, introverted person. At a big party, I'm like Bambi in the headlights," Watson said.
"It's too much stimulation for me, which is why I end up going to the bathroom! I need time outs! I get anxious. I'm terrible at small talk and I have a ridiculously short attention span," she added.
