Why Did My Father-in-Law Interrupt Our Morning?

Okay so this morning my father in-law was blowing my husband phone up but his phone was on vibrate I heard it but didn't want my husband to get up (we don't get to sleep in that offten) so my husband woke up to some sex (which I've been wanting all week but didn't bother him he worked six days straight) so in the middle of getting some his dad was yelling his name through the door -__- (his parents live across the street from us) ugh I'm like no! not a good time lucky for me my husband finished then left
