Why I respond to some blogs and not others

I come to this site almost daily. I see blogs that seem to pique my interst and others that don't.
I grew up caring about others and when i see hurting I want to respond to let the person know there are ears for listening.
I don't make judgments, I do care about others and want to see happiness here. Its not always going to happen but I feel if I add just my $.02 to the blog maybe it will be a factor in helping the,
Before I respond I see what others have to say if there are other people replying to the posted blog. A few times I have seen answers that really do not pertain to the blog, but I overlook them as those people most likely feel they are contributing.
I still don't have the tenacity to write and without any stic-to it ness I feel my contribution other then adding a story can be to help the person in need of support get encouragement from me.
Most of the time I've been there and done that or I myself am going through a similar crisis at the moment.
The wrong remark can often leave a sour taste especialy if I am identifying with the person as going throught the same stressors. My tag line is be kind to others becasue no one knows what others are going through.
