najida, your line of thinking applies to all those who have ever suffered a great loss. I have a niece, who in her twenties suddenly lost her young husband in an auto accident. For a long time, she couldn’t go to the Mall, because she was saddened by all the young couples there...by all the vibrant young women who still had their beloved guys at their side.
So, all the couples in her town should have stopped going to the Mall, out of fear of hurting the widows who were still grieving?
Think about it. Whose job is it to get over the grief, the loss, and yes—the guilt? The general public? Or the one who suffered the loss?
The issue is private space versus public..... mail (your home) versus venturing into the mall (public).
For example, if your niece doesn’t have the right to tell people what to do at the mall, however, if she doesn’t want to invite couples into her home, that’s her right and perfectly OK.
If a couple knocks on her door, insisting on talking to her about the joys of marriage and asking her questions about hers etc, she has the right to be pissed off and tell them to leave. And even tell them to never come around again.
