Hi Rachel. I think he is just being a gentleman. Because if he likes you, he will say more sweet things than that.
If a guy says "You are a sweet and kind young lady" to you twice and stuff, do you think he likes you or is he just being a sweet gentleman?
There are both posibilities if he is very frank then he is a sweet gentleman or if he is a shy guy he really likes you because shy guys hezitate to a girl that they like her...Now its upon you...
He is being a gentleman. A guy should say more about what he likes about you other than you are sweet.
Yo yo yo the answer is he became a sweet gentleman just like me...good day rahel!
