It's common for me to hear from others that Arav speaks well in English..(we all know how important that is;))).Of late he has started to talk a lot in Tamil. Where in English he uses sentences that are clear in grammar and pronunciation. In tamil i cannot vouch for the same..but then i still enjoy the way he says it..baby talk gets in the way when he uses the words..sometimes he says..Vaden for varen..which sounds cute to me...
