"Ugh! Why did you have to tickle me like that? It's not funny!" Hailey exclaimed, crossing her arms and glaring at the person who had just tickled her armpit. "I was just messing around, Hailey. Lighten up," the person responded, chuckling. "Well, I don't like it! It's not funny to me," Hailey retorted, feeling frustrated and slightly embarrassed. "Sorry, I didn't realize it would upset you so much," the person apologized, realizing they had crossed a line. "Yeah, well, now you know. Just don't do it again," Hailey said firmly, still feeling annoyed by the whole situation.
