I tried that with another co-worker I was interested in many months ago. Didn't work, lol.
I actually tried that with yet another co-worker I was interested when I changed shifts, and it SORT of worked, as she included me in conversations... but she's married. But we're friends now, lol.
Oh but with the married woman we take breaks in the same areas generally, and those areas are small, and she sits in a place that's convenient, right by the men's bathroom at the corner of the table.
