People go on a trip mainly for leisure time. They go to spend time with friends and family, get healthier and stronger by example, going for hiking, bicycling and so forth. Sometimes, people go for educational reasons. Maybe to take a test, to develop more skill on a particular subject.
Hope this is what you are looking for! Goodluck ;)
A feeling of mystery<em> </em><em>is an effect caused by the rhyme in this stanza.
</em>
Up to the 4th verse, the stanza follows a syllabic rhyme ABAB pattern where final words end with similar vowels sounds. This arrangement provides musicality as well as a sense of calm given the use of <em>natural visual imagery. </em>
The 5th verse continues the rhythmic pattern, although it already creates tension by introducing a strange ocurrence "<em>the sound of a hound in the distance".
</em>
Verse 6th then ends the stanza by breaking the rhyming pattern maintained and leaving the reader with a sense of mystery and tension about the unfolding of events.
