It teaches us to be concerned for the welfare of Gods people to mourn for our sins and asking the Lord for his forgiveness when we fail him
Lamentations was meant to be a sad book
well really if you have a car, you can simply drive to church and make yourself better
When you pass a swift, upset sounding fart that makes you look like a dipshit.
On the morrow I shall pass a quick Barry's Lament.
