Participate(Aldrin)

="I think that dad will be home late as he is a participate at a meeting" said by my brother, looking up from his homework. He staring at the phone," Do you want to call dad?" I asked, " Yeah,this homework is confusing." We looking in the window to know if dad had came home or not. He hasn't home for 1 hour and he hasn't come yet and finally we contact dad and saying," I'm in the middle of a traffic jam, I might go home late. I participated the meeting yesterday, not today!"=
