In describing people, there are two things that we often focus on , appearance (physical description) and personality (mental description)
Gerunds are defined as verbs that take “ing” at the end, while infinitives refer to verbs that have “to” at the beginning.
Expressing likes and dislikes doesn’t mean being aware only of the words and expressions used for this purpose but of their usage as well.
Talking to people means communicating your ideas and exchanging views with them. That may include expressing your agreement and disagreement.
Expressing opinions the right way is valuable as it establishes a fruitful relationship with your listener, especially negotiating a topic.
