On one day a year, nobody texts their crush (unless there’s an emergency).
This means that if you don’t get a text from your crush, then perhaps she/he might like you back. In any case it relieves some stress and you have an excuse not to text her/him.
I didn’t text my crush on National “don’t text your crush day”.
On September 24 you text your crush and it’s ok if *insert pronouns here* reject(s) you at least you don’t have to wonder what if
You: hey it’s National Text Your Crush Day so, wanna be my *were gonna say person*
Crush: omg yesss
