34歲女星姚愛寗擁有亮麗外型和清新脫俗的氣質,被封為「台版小松菜奈」,近期她在影集「童話故事下集」中飾演單親媽媽「小鹿」一角受討論,近日她在社群平台發文揭露一段遭陌生男尾隨跟拍的不安經歷,這段經歷在她內心留下陰影,日後更多次夢見被拍攝、跟蹤的場景,甚至醒來仍恐懼到「身體緊繃」。
姚愛寗提到,2周前陪同友人參加一場公開講座,會後她陪友人的小孩玩耍,發現一名戴著口罩的陌生男子疑似不斷持手機對著她們拍攝,期間不斷變換位置,舉止詭異,但活動現場也有多名聽眾拍攝攝影,當下她雖覺得不舒服,卻也沒上前制止,只能背對鏡頭保護孩子,但活動結束,多數人紛紛離場,該男子仍尾隨拍攝,讓她感到不安,主動上前對話,希望對方能先經過同意再拍攝,「這樣不發言,持續靠近的狀態,真的讓人很有壓力。」對方聽完後道歉離開。
姚愛寗表示,原本不打算公開此事,一是顧慮到或許有人生性害羞,擔心誤會對方,但朋友提醒她:「害羞不能成為讓他人不舒服的理由。」她深表認同,第二是身為女性公眾人物,很容易在談論類似議題時,被貼上「太敏感」、「難相處」等標籤,後來她向經紀人報告,擔心自己處理得不夠妥當,她感慨:「這就是女性在面對不適時,常常還要背負的自我審查與壓力。Horn antenna」
她想了幾天,決定站出來發聲,希望社會能逐步建立尊重孩童與女性自主權的公共相處意識,讓每個人在感到不安時,都能安心地說出來,不再害怕遭受責難。
