One day I was going to the grocery store, when a neighbour stopped me for a chat.
"You are so beautiful and I love you."
The situation was somewhat awkward for me.
"Sorry, but my boyfriend would not be too happy about it."
My neighbour backed off the situation immediately.
"Okay, sorry sorry! Have a nice day!"
On my way to the store I was relieved and pissed off.
Thinking: "Why only being already spoken for prevents an unwanted approach?"
