i kept thinking i had left the front door unlocked whilst i was on vacation ! that is a terrible feeling . i saw a movie where a family actually left their kid at home . that would be the worst . sounds like home alone ! yes i was so anxious the entire time that i could not even enjoy myself . well i hope everything turned out ok. maybe you can send a friend to check your door .
The thought of a child being left home alone triggered the feeling of anxiety.
