Like boredom. Yes, there was plenty of that when she was holed up in someone else's home hiding while they were on holiday. Or when she was able to find a bit of shelter in an abandoned car. Utilizing Muggle public transportation offered plenty of opportunities for boredom. But, at least then she had the thoughts of what she was going to do next to occupy her mind. An idle mind was a dangerous enemy. Spending her days inside her tent or sitting just outside of it watching the village activity sounded like a future filled with nauseating boredom. Even late night walks when everyone else had gone to bed wouldn't likely improve the situation.
