On Thursday I saw this happen and I sort of liked it, what does it mean?

Okay well on Thursday at Lunch I saw sitting there and then this Chubby Hispanic Girl came up to this skinny Hispanic Boy and said in a Love Way "Hey Hernando........" And then she took her hand and started caressing his hair and messing it up and I sort of got turned on by this.Then after she finished, she plopped a big kiss on his cheek and then walked away, that also turned me on.I had a crush on this Hispanic Girl last year, and I liked what she was doing to that Boy.I want her to do it to me, should I ask her out?
