Why do I get told to stop flipping out over everything?

So yesterday after work I was in my way to the bus and some desperate man came up to me. He said hi to me and wouldn’t stop looking at me. He said he saw me walking out of the pet store and tried to say hi to me. I don’t understand why he stopped over here.
I told him that I just got off of work and I need to go home. He said, “Well I wanted to take you somewhere. Maybe sometime for dinner or I can take you to a movie. What do you say?”
I just looked at him and asked, “What do you want from me?”
He said, “I’m just trying to make friends and meet new people and I thought you’re so beautiful. Let me take you somewhere. I can take you home.”
The bus came and I got on. He said he wanted to see me again.

Seriously?! I can’t believe that happened?!
I told my besties about it and I was yelling. They said I didn’t need to yell and I did the right thing. My female best friend said, “Well did he ask for your number?”
I said no and I just got out of a horrible relationship. Then she said, “Well there you go? You said what needed to be said. He probably thought you were beautiful and wanted to talk to you. If a woman is beautiful of course guys are going to look. You really need to chill out.
Then my guy best friend said, “It happens to a lot of people and if a guy finds a girl attractive, they WILL notice and will wanna talk to you. I’m a guy. I know this and we don’t play around with put feelings. We’re honest about it. Stop flipping out over everything. It’s not a BIG DEAL.”
I told my dad the same thing and he said, “Well you were honest right? You stuck up for yourself. He probably found you attractive. I mean you’re an attractive young woman. Quit tripping. And stop taking things so personally. You’re an adult young woman not a child. Act like one. You know what is right and wrong.”
I’m surprised nobody flipped out. If I was a kid they would’ve flipped out. My dad asked he hit me and I said no.
