i shift automatically to 'tu' sense if i am comfy with the person.. def. not to elder ones..but here till the moment you get to know of how big they are!!! its quite a long time!!😳
Yahan pe sach mein pata nahin chalta and hence I use 'you' more than 'aap'. Lekin mera aap bolna has nothing to do with comfort level. It's a habit jo sirf kuch hi logon ke liye change hui. 😛
