Congratulations!
I think it is a lovely idea, but would also consider a Malvina Reynolds' song that I love;
If you love, if you love, love, love me
Plant a rose for me
But if you think you'll love me for a long, long time
Plant an apple tree.
Apple trees take up more room than roses though!
To think that London, or anywhere else for that matter, does not belong to any one demographic
