i'm the older sibling so i know how it feels.. we dun really say out things like 'i love you' to our siblings, and they keep thinking we dun care about them, but we really do deep down..in fact more than them,we just express our love for them through our actions from the bottom of our hearts and rarely say touching things. they're annoying at times and we just wanna get rid of them but seriously.. we can't live without them.. that's the case for me at least.. and if i'm not wrong Tom as well..
