There's a girl at work (really hot, a few yrs older than me), who I get on well with. She's naturally very chatty with everyone, always willing to help etc.

Since startin my job a month ago, she's generally taken an interest in me (when I say interest, I mean getting to know me e.g. where I live etc). I've done the same.

BUT, she is very career minded. I only have her work mobile, which has only been used for work-related communication.

How could I send a txt about something other than work, and not apear to be "trying"? Very subtle flirting perhaps.
