As for the reflection on reading habits and taking into account the different images offered, the people that are sitting around by the library seem to be reading different books about topics they might have chosen themselves; maybe science fiction, novel, and so on. Therefore, I reckon they feel relaxed, calm and happy because they are enjoying the reading surrounded by other people.
The image where it appears a boy and presumably his granny, the abovemetioned one is reading a book on plants, so perhaps, he is studying or looking for information from school; I guess he has not chosen the book by himself. As well, the pupils in class are reading some academic books the teacher has asked for.
It called my attention the man who is standing on that high stool; he shouldn´t be very comfortable, still, he is reading a newspaper that seems to call his attention in detail; so, he may be enjoying this reading, chosen by him indeed.
Furthermore, there is an elderly person who appears to be reading something from a small device. I imagine she is discovering happily a new way of reading and she feels very interested in that.
The genres that I enjoy reading in my native language are the romantic novel, adventure and science fiction ones. In English, that is the other language I can speak, I tend to read more types of texts, just because of the fact that I am learning new collocations, idioms, and definitely, I feel I am acquiring a wide range of vocabulary, what enriches this. Therefore, as I have mentioned, I normally read different types of texts depending on the language I am using; that is due to academic or educative factors.
I´d always loved to read in paper format, maybe because I´m a fond of paper and its smell… call me weird! But, I don´t really have a Tablet or E-book, although it is true that I consume a lot of electronic reading, via internet, news, and so on.
Last, but not least, I love reading at night, during the academic year, before sleeping to feel more relaxed; and in summer, when I have more free time, I love reading in the early afternoon, specially if I go to the swimming pool or to the beach. Then, I can spend the whole afternoon switched off from reality ;)
