Granny

I was having dinner with some friends at a hawker centre last night when a 2 - 3 year old boy came up to our table, looked at me and called me 奶奶! What! Hello! In what way do i resemble his granny? Was totally devastated.... actually I still am being huanted by his cute little voice going 奶奶... 奶奶... 奶奶... Argh!!!
