Goodness, Strops - does the worry ever end? It might be worth "cultivating" this particular FB friend, if she can tip you the wink if DD is falling off the wagon health-wise.
BP walk sound like it was bracing and restorative! We've been mostly walking around car showrooms. I'm bewildered by choice, although I did fall for a bright orange Yaris with all the bells and whistles (costing about double what I have to spend).
Slug-infested student hovels are surely a rite-of-passage? I lived in a delightful place in my 3rd year (with our mutual friend, MI) which had a very sluggy basement kitchen. When we went home for Christmas we sprinkled slug pellets all over the floor, and came back in the new year to find twenty-six rock-hard slug carcasses welded to the floor. Bleurgh.
