Though simple,the powerful message of this animated short is presented short and sweet and makes the viewer think(and learn from the character's example of jumping to conclusions.)The ending may seem sudden but maybe the creator wants the audience to 'guess what happens next' after the ending.Would his outburst lead to punisment by his parents(if his sister should tell on him) or his apology and sister's forgiveness or just stubbornly refuse to admit his mistake,who knows,as this animation only gives a view into a problem between two characters any viewer would not know so much about(besides them being siblings and active gamers.)Anyway,this is quite a good way to remind anyone that the brain should work before the mouth as everyone will have to deal with such a problem in real life(and a clever way of using a game reference to get the message to the viewers.)It would be great to have more of this,to not only entertain but also make everyone reflect on their lives,so keep it up!
