My dads supposed to arrive home tonite from his long trip... im so scared :'(?

so my dad was gone for 3 weeks... hes coming home late tonite. my mom and bro went to go pick him up at the air port like two hours ago, and then my bro called me at home. he asked me if dad called, and he hasnt. i asked him when my dad was supposed to arrive, and he say 40 minutes go but then silently said just kidding. my mom said they would be back from the air port at about 10 or 11 and there not home yet. im crying right now, becuz i just hope hes ok and he arrives safely. im tearing up so much and just hope he comes home safely. any ways i can keep my mind sorta off of him? i miss him so much!!! any words that may keep me from crying? could have just be a flight delay or something... but idk.. please help! thnx so much
