Final answer:
Despite an abrupt manner, the person is actually very nice, indicating that one's initial impression may not fully capture their true character.
Step-by-step explanation:
The phrase 'Her manner is particularly abrupt' suggests that the person in question may come across as confrontational or abrupt in social interactions, which could be perceived as being hostile or rude. However, the follow-up 'but actually she's very nice' indicates that despite this initial impression, the person has a kind nature. This shows a contrast between the person's manner and their underlying character, signaling that appearances can be misleading.
The description of Kaitlin and other scenes depicted showcase the complexity of human behavior — how societal interactions can be shaped by personal attitudes and the importance of not making quick judgments about a person's character based on their external demeanor.
