Why not just be glad he had the respect to come?
@ladybeachbum :
I think that question comes with some qualifications. If the person found out last minute about the service, or they dressed in a manner the dearly departed might appreciate then sure. That's something however that might remain unknown.
However in my opinion if at all possible a person should attend certain events with some sense of fashion decorum. It not only shows some level of respect for yourself but also respect for the occasion. I hear all the time that well society has changed and people want to be comfortable above all else.
Apparently that is true. For example, people wear clothes to church now that would have been unthinkable 30 years ago in most congregations. In that vain a buddy of mine and I had a philosophical discussion about this some years ago. I asked if a person was invited to spend an hour with the POTUS in the Oval what would they wear?
We both concluded that the average person would probably wear some type of business or at the least business casual attire. Then I said why would they wear that for a president, but attend worship services for the King of the World in far less? The point was in most cases it's not that people are not capable of dressing appropriately for the occasion, it's more whether they feel the event merits them to do so.
And perhaps that is the reason the guy in the T-shirt got disapproving looks. Though with the caveat we'll never know why he showed up that way or what's in his heart.
