Electricity

I was just showing something to A, to do this I had to sit on her desk. Anyway, showing her the thing involved close contact, faces getting near.

'Did you feel that?' asked A.
'Feel what?' said Louche.
'That electricity, when are faces get close together I feel sparks'
'I say'

Further testing has revealed that if either of us get into close proximity we both feel tingles under the skin.
