Never started this too well. Got home And W seemed a little offish. so thought better not ask 'how has your day been' so asked 'you okay?'. FAIL!!!!! Not sure why I did that !!! Of course I got the answer 'yes I'm fine '.
Try again another day!
Don't get discouraged; it's such a small thing in the scheme of things. Stick to "how was your day?" or something more specific that doesn't get at her feelings per se.
