So step 1: you dig a hole in the ground. (I won't dig. My hands are too precious and last time I dug something... I found a patch of earthworms *shivers*)
Step 2: we will name that hole 'love'.
Step 3: we open a matchmaker service. We'd find skeptics and tell them that for a small fee we can make them fall in 'love'.
Step 4: push them in the hole we named 'love'
