Evening Mollie. 
this watch is certainlky interesting, it picks a signal up as long as you are within 1,200 miles of the transmitter, but it will work in countries that have the same signal, like the US, Japan, Germany, i don't know how often it needs to pick the signal up, maybe just when you buy it, also when you change the battery.
We don't have Marmite, not sure why, just have never ordered it.
Never heard of putting mushrooms in the light, they grow in the dark, i know that.
My lad sent me a text, the one that was round earlier asking if i fancy going out for brekkie in the morning, o/h at work anyway, of course i said yes, so thats sorted.
You certainly need the roof sorting, thats urgent, but not sure if they can work on the roof if the winds are strong.

Yes, very handy to have an Amazon gift voucher, i usually order about 4 things a week, had only just done an order for about £54, the voucher would have been handy.
Dropping scenary etc on your foot is dreadful, omg what an awful thing to happen, that may never be the same again after that, poor lad.
Yes, roll on Spring, looking forward to it.
Have a good evening and sleep.
