Don't want to arrange lunch in case we get delayed. Easier for us to take picnic.
We would love to come to yours, though if that's ok. text me your address so i can look it up on maps.
Bit wary of arranging to meet outside in case it's snowing or similar (optimistic ain't I)
Don't want to put you to any trouble, so if it's not ok PLEASE let me know.
I can text you from Lancaster-ish and that'll give you a bit of warning??
