Many of the heros will not attend the other hero function which belongs to his own family. Few hero's are not interested to celebrate audio function also. But some hero's will celebrate Audio function by inviting all the industry young heros thinking that everyone is his relatives. Nani is one of the hero among them.
Frankly for the talent which Nani has anytime minimum 3-4 will directors will follow him. So, he need not to do friendship with other heros. But, if he thinks like that why he becomes Nani. See, recently he visited the Audio function of Nitya Menon's 100 days of love. Yesterday he came to Babu bangaram audio launch and said he want to see Venkatesh in masala movies everytime. Today he tweeted about 'Srirasthu Shubamastu' trailer. By seeing all these what can you understand?
He is socialising with all the heros in Industry and encouraging them. Nani is behaving very good with all the heros. We can say he is a good person by seeing his face.
