How can a euphemism function for unpleasant words or phrases?

Explanation: Euphemism is used to mitigate unpleasant words and phrases by using words that have the same meaning but not sound so uncomfortable and unpleasant, instead of explicitly unpleasant words, which in addition to being unpleasant can be considered offensive, vulgar, etc. For example, a social drinker can be used instead of the word alcoholic.

Euphemism is therefore used to avoid unpleasant words, which means avoid possible confrontation, then to avoid hurting one's feelings. However, euphemism can also be used for negative purposes when, by substituting a particular word for another, one may be misleading deliberately, or intentionally belittling the true meaning of what is said.

b. by using a metaphor ingersoll explains how artistic thoughts address social issues which clarifies his idea

free time is when all my homework and chores have been done for the day and i am "free" to do things that i enjoy doing.

usually i spend time watching television. as my favorite tv shows come on at specific times, i make sure that i finish my homework and chores well before the shows. otherwise i will have to miss them. mostly i manage to watch the shows but sometimes extra homework or chores may cause me to miss a show or two, but it is rare. anyhow if i know that i am definitely not able to catch a show in time, i will just set the video recorder to tape the show sothe evening when the weather is fine, i sometimes go for a stroll around the neighborhood with my friends. this is the time when most the neighbors have come home from work or school. we say hello to those whom we know. they are mostly friendly people and they acknowledge our greetings. once in a while we come upon unfriendly neighbors but we just ignore them and carry on. that i can watch it later.
