Today but she's working till 6pm .
Think I will buy her something nice was looking for some advice as I'm not sure what to give her .

Any ideas would be most welcome .

Maybe a Fitbit or something similar? I remember you saying she goes running with you.  Flowers, wine and chocolate are always a safe bet for a woman IMO.

In failing that, Mrs Timbo might be able to knit her a tea cosy at short notice.
