Should I throw out the pictures of him?

I'm at my grandparents house and there's all this pictures of this little boy named Jacob. He's not even there grandkid and they love him more then me and my brother who are their only grandkids. And they spoil him so much. Me and my granmas birthdays are on the same day, during a hoilday and they've never once celebrated it together. And we live only 4 houses from them and tey dont visit but they visit jacob on his birthday and he lives 18 hours away. An we cant visit cause my mom only gets like two weeks off a year from work. And last night my granparents and mom got in a fight and long story short. They basically don't wanna take me back home for the 4th of July because their dog can't come. And they said if the dog can't we won't. And my grandma yelled at my mom and said someother things about her and me. And basically she doesn't even want me down here visiting her and that I need to leave and that she basically said se doesn't like me or love me really. And she hates HATES my dad, for no reason, and my dad things it's cause I'm half him. So I'm really pissed off right now. And my dads coming to get me in like two days. And I'm really pissed because right after they invited Jacob to come and stay with them after i leave. And they have two pictures of my mom in there house. She's there ONLY child. And like 5 of me and my brother. And 20 of Jacob and his mom. And there all kinda in this little spot. And I'm so upset I just wanna take the pictures and throw them out the night before i leave. So I can't really get introuble for it.. Should I throw them out, I'm really mad right now. Or just take them and hide them
