My mum used to teach children with special needs.
She had an outing with one kid with down syndrome, just doing normal things, going around town and the like.

She was paying for some treats in a shop when she heard his voice behind her: 'I love you', and my mum, knowing that people with down syndrome have the tendency to be very affectionate, said 'Aww, I love you too'. He replied, 'no you don't understand, I REALLY love you' and my mum turned from the shop assistant to see him, wang in hand, smiling broadly at her.

From then on, whenever my dad wants to embarrass my mum he shuffles up to her, ginning and gurning, and says in the most simple voice he can 'I REALLY love you'.
