<human>: Well,  a close female friend of mine went to a nice dinner with her boss. She is 23 years old, he is around 40 or so. No, she is a paid intern at a company, and it is not unusual nor completely unexpected for bosses to take their employees out for dinners and lunches as a reward for work well done, or, in this case as a pre holiday break celebration for the end of the year. 

now, my friend went to a nice dinner with her boss, and everything seem professional to find. However, at the end of the dinner, the boss mentioned to her that he does not get to have much fun, and that they should do it again. He then kissed her on the cheek. He also sent her a text after the date saying, that he had a good time and that they should do it again.

Unprofessional or...? The girl in question was a little weirded out, I might add. 

Just curious on thoughts of potential unprofessional behavior...

Could you distill the essence of the text into 1-3 sentences?
