I miss my brother for one very important reason. He is my black hole for gossip/opinions/theories - whatever I tell him stays with him, in a galaxy far far away from mine. Nothing I tell him is likely to come back and bite me. Now that he's away, I have to remind myself to keep my mouth shut. Sometimes I forget other people talk too. I could've avoided some recent faux pas if I'd just called him up and vented.
Its not that I don't have anyone to talk to outside my house. I thankfully get my regular dose of conversation and random small talk, just not with anyone as
perfect as my brother. You need someone like that - who you can just tell (almost) everything on your mind, who's biased towards you, who's known you (relatively) forever, and who will laugh at your stupid insider jokes and vice-verca. Plus, bhaiya analyzes the smallest thing as much as I do; so we can talk for hours.
