I saw you with another fellow, but I don't care,
You do not love me any more, but I don't care.
Perhaps you think you made me mad, but I don't care,
Some other girl will make me glad, so I don't care.
This postcard was sent from 'A Friend' to Miss Rebecca
Mean+ney in (I'm guessing) 1911.
I think if 'mr. friend' didn't care about dating her, he would have spent the time and money to buy the postcard and stamp and call her a meany.
Here is a scan of the back of the postcard . . .
USA stamp 1908
