so I'm beyond heated my son had said a cuss word an which I got on to him for it an I guess he said it again so my 8yr old brother thought it was funny to take matters into his own hands ( inform of my other cousin) an punch my 3 yr old son in his face making him cry then try to shut him up before I heard him but I got really good hearing so I get up to see why he was crying my son's nose is red an my brother sitting there laughing I tryed to hit him but he ducks an my grandpa gets somewhat on him an told me to take my son in there but I'm not satisfied I'm sorry but idgaf how old you are or who you are never put ur hands on my child I feel like being petty af an punching him in his nose but I have to much anger so I guess I'll just slap him hard when I catch him am I wrong
