The two lads were having a conversation with sticky notes, at they're usual spot when Louis suddenly asked 'do you still want to hear my song?', to which Niall replied with 'yes please!'.

 Louis then handed his earbuds to Niall, who put them in. Niall then wrote "I can't hear anything"

Louis then signed 'I'm D-E-A-F'

 "You're deaf?" Niall immediately assumed that Louis was deaf, from the weird hand motions the feathery haired lad had done.

Louis nodded.

Niall took a deep breath and spoke slowly with a soft tone." You're still beautiful" to which Louis blushed and looked down.
