Given a travel related situation, and given a specific question about the situation, summarize the question into a title

[EX Q]: Specifically, I am taking the train from Taipei to Keelung, getting off at Badu and going to Pingxi, and then returning at night.

Do trains tend to sell out in Taiwan, or should I be OK purchasing my ticket immediately before departure?

[EX A]: In Taiwan, must you reserve train tickets in advance, or can you buy tickets a few minutes before trains are supposed to depart?

[EX Q]: Having spent a bit too much time in the pocket of my trousers, the name and emblem of my country have been erased from the front of my passport. The relief is still visible if you look at it under a lamp, but at first glance the front is entirely red with no text or graphics. To know what country I live in, you'd have to look at the page opposite the laminated information page.

In addition, the pages are rather ragged, although there are no tears, water damage or similar.

Is my passport now "damaged" enough that I will not be let into countries with strict border guards? It has worked fine for the occasional passport check at airports in Schengen, but I suspect border guards in Turkey or China may be considerably stricter.

[EX A]: Name and emblem of country no longer visible on front of passport -- is it "damaged"?

[EX Q]: Context: I am looking into settling down in Berlin and I would like to know what to expect from summer time in term of public activity/cultural events.

What I've observed: I've noticed each city has its own pace during summer time, some cities becoming more active (more people in the city, more cultural/social/outdoor activities), some others becoming more quiet (less people in the city, businesses opened limited hours) or not being impacted at all.

Question: Is Berlin experiencing a decrease in public activity during summer time (July and August)?

I am especially interested by the following aspects:

Are the streets noticeably less crowded during summer time?
Is the city known to experience an increase in social/cultural activity during July and August? (example: outdoor cinemas, streets/parks festivals, music festivals, fireworks, ...)
Is there times during summer when public places (especially coffee places, libraries and co-working spaces) are expected to be open only during limited hours (or to be closed)?
