At times, I have been guilty of doing one of these, be it intentionally or unintentionally. Tactless remarks/deeds hurt people, especially those with a backstory. The negative impact I or we bring to other people can transcend the abysmal dimensions of their insecurities.
Food for thought: Mind the repercussions of what we say or do to other people. Making people feel bad about themselves will neither get us to a higher elevation nor will make us better persons. Just because the shoe doesn’t fit doesn’t give us the license to strain other people.
People who bash homeless folks. You are inconsiderate, ignorant and most of all a shitty human being. You obviously don’t understand how unforgiving life can be… especially without family &/or friends.
