Hey, @aggroed!
There is a very famous quote of Lucius Annaeus Seneca;
One of the most beautiful qualities of true friendship is to understand and to be understood

First of all i would like to say you that you are blessed if your span of friendship is of about 30 Years Wow!
This thing indicates true friendship does not need money or status it demands sincerity and understanding only. The above traits which you mentioned in your blog are actually the traits of REAL FRIENDSHIP.
Absolutely right you said;

Looks will fade. Brains will slow. But your heart will keep being kind towards others if that's what you cultivated.

I have also a strong bond for past 18 years with my Friends who are cousins in relation to me, my age fellows as well. Your blog reminds me them as they are working at different places of the glob at the moment but still we have bond and we are in contact to each other. Your scenario is entirely different then ours, as i said you are blessed because they all are with you.

How beautiful example of humanity and Friendship i just read via this blog.

Thanks for sharing such motivational wording it will definitely boost our relationship with our friends zone.

Stay Blessed, Steem On!
