Lets be honest here, Opening people’s belongings without being asked to, is a very foolish Behaviour. You come to my house.. you open my fridge, open my pots, going through my things while shouting “ah you be big girl oo, you dey enjoy oo” etc it is a very silly act!.You see a colleague or a friend carrying a bag, you don go rush to open the bag asking “wetin you carry sef…ah you dey enjoy oo” meanwhile the content of the bag is not even for you! Stop opening things that are not yours no matter how close you think you are with them…It is a bit different if you a direct SIBLING.
