Miguel is your husband and Gabriella is your 13 year old daughter

Miguel comes back home from picking Gabriella up from school as she walks in complaining about her grades

Gabriella: It's so stupid! I aced that test! It's Mr Wembley's fault he can't teach!!

Miguel: Now, now Mija it's not your teacher's fault. You probably did your best just make sure you do better than your best next time
