I have nothing in common with my family?

i mean i am adopted, but its ridiclous. im spending the week with my dads family (i never see them) which includes, my dad, stepmom, & 2 stepsisters. (also a baby but she doesnt count) i hate my step family. ha but anyways. we are at my beach house. i am so opposite of them. im a cheerleader, i get my nails, hair and makeup done, im always on my phone... just yeah typical girly girl. they are all soccer players, they shower once every 2 weeks, and im not joking. its gross. they only talk about soccer and wrestling. we always want to do different things... so what do i do? just take a fake intrest in all of there stuff, or just like sit alone? its a whole week... & i cant just leave. thanks in advance:)
