Fair warning

To give y'all an idea what kind of mood I'm in today, I just reset my desktop wallpaper to Bruegel's Triomf van de Dood (Triumph of Death).

What is love anyway? (for cuorefelice34)

1. Live is like a razor blade: double edge for double pain.
2. Love is like a bottle of gin, but a bottle of gin is not like love.
3. Love is a stranger in an open car to tempt you in and drive you far away.
4. If you don't cry, it isn't love; if you don't cry, then you just don't feel it deep enough.
5. And love is real, and though I realise this is not a deep observation to those of you who find it necessary to conceal love or obscure it as is the fashion.
6. In honour of our beloved revolutionary sweetheart: Nothing more, nothing less, love is the best.
