Sami and her father go to the park to play. There, they see Sami’s teacher. The teacher is surprised to see Sami’s rambunctious behavior, as it’s different from the Sami she sees at school.

先生(せんせい):
学校(がっこう)でのサミさんはすごくかわいい(さわ)やかな表情(ひょうじょう)をしています!」
“At school, Sami has such a cute and delightful expression!”
パパ:
「ちょっと(ねこ)かぶってるんだなぁ…」
“She's just putting on a front, isn't she...”

Key Points

1(ねこ)(かぶ) = “put on a front”
  • This idiom means hiding one’s usual nature by acting innocent, quiet, or well-behaved. Here, Sami’s father says that the sweet demeanor her teacher sees at school is an act.
2Casual speech: (ねこ)(を)かぶっている → (ねこ)かぶってる
  • The spoken form drops the object particle and contracts 〜ている to 〜てる. The fuller wording is (ねこ)をかぶっている.
  • Here, 〜ている describes the front Sami maintains at school, rather than the literal act of putting on something at that moment.
3学校(がっこう)でのサミさん = “Sami as she is at school”
  • Adding after 学校(がっこう) lets the location phrase modify サミさん. This wording sets her school persona against the more active Sami her teacher is seeing at the park.
4The father’s softened, reflective judgment
  • ちょっと makes his criticism less blunt, like “just” or “a little” in the translation.
  • Explanatory んだ presents the act as the reason for the difference, while なぁ sounds reflective.
  • さん is an honorific suffix attached to a person’s name to show respect and social distance, roughly equivalent to “Mr.”, “Ms.”, or “Mrs.” in English, though it’s used far more broadly and doesn’t specify gender or marital status.
