Write about a time when you didn’t take action but wish you had. What would you do differently?

During my college days I was in love with a girl who saw me as a friend.
Immature me, didn’t know how to express my feelings, stopped talking to her.
She tried many times asking me what’s wrong but I didn’t express.
On the last day of college after we got dropped by the college bus in the city I saw her in the bus stop walking towards me.
We both had eye contact but didn’t talk. This scene will stay in my mind forever.
Had I took 10 minutes and expressed everything to her, giving her time to think, she might have considered me.
Good day to you🫡.
