When calling or knocking at someone’s door, it is important to identify one’s self. One should never say “it’s me” as this is incorrect. Rather one should try their utmost best to identify themselves in the clearest manner possible.
Whatever the host offers you, accept it wholeheartedly. It could be a particular seat, a cushion or a stool. Accept whatever the host gives you and accept it gracefully.
One should not sit in the place which belongs to the host. Most people have their favourite places within their houses (their normal place where they sit). The last thing one would want to do is to sit in the place of the host, unless he invites you to sit in his place.
If other guests enter the room and no seats remain, we should be willing to give preference to others and give up our seats. Especially if an elder person or a person of knowledge enters the room, we should stand up and give up our seat.
One must not open a closed closet, look inside a box, or open a wallet or even a wrapped package, including anything that many be covered. This goes against the trust the host has granted you, and this is a sign of a hypocrite.
