You have no idea...
At my job at the register I had a customer that could have been my grandfather and passed me a note asking me to join him for lunch... I wanted to run and hide right then and there, it took all my willpower to act unfazed and just laugh it off till he left.
I'm sorry that you have to experience that, I really hate when men do that, do their brains made out of peanuts or smthng? How did they process that its fine to flirt on someone years younger than them, what a creep.
There are really a LOT of creeps like that, I had a man I had known for 2 years asking me some really kinky stuff. He was older than my grandpa! After that I don't trust men even If they are elders
Disgusting creep, flirting with a woman whose probably the same age as your daughter
