反諷式打招呼（對久違的熟人）
反過來用核心意思開玩笑：對方明明是熟人，卻故意用『陌生人』來招呼，突顯『你太久沒出現，都快變陌生人了』的親暱調侃。
joking greeting · noun · B1
A joking, warm way to greet someone you know after a long time apart.
好久不見！
核心畫面
You can picture a stranger as someone from outside your circle — a face you've never met, who belongs to the world beyond the people and places you already know.
可以想成：stranger 是圈子外面的人——一張你從沒見過的臉，屬於你所認識的人和地方之外的那個世界。
From the word’s history
From Latin extraneus 'external, from outside' (from extra 'outside'), via Old French estrangier 'foreigner'. A stranger is literally 'one from outside' — outside your circle, your town, your acquaintance.
來自拉丁文 extraneus「外來的、外面的」（源自 extra「外面」），經古法文 estrangier「外地人」而來。stranger 字面就是「從外面來的人」——你圈子外、你城鎮外、你認識範圍外的人。
