I am sorry for your loss.
I am sorry for the lost opportunity for a poor, underemployed, or homeless person to wear the suit that you could not bear to wear again.
You denied yourself a blessing by failing to bless an anonymous stranger.
All of us neglect acts of christian charity from time to time... This human being is grieving... and shared a private thought. Christ commands us to love our neighbor not only in worldly donations but in spiritual charity as well... perhaps you have denied yourself a blessing.
*I am sorry for the lost opportunity for a poor, underemployed, or homeless person to wear the suit that you could not bear to wear again.*
You sound like Judas lecturing Mary Magdeline. Who gives you the right to judge how someone else grieves? You come across as a pompous, self- righteous jerk.
There are times for criticism and there are times for silence.
Figure it out.
