Sustaining a friendship=care, concern and being truthful

I realised/found the joy of being ultimately truthful to friends.
It's just like letting go an ultra heavy bag of something, perhaps a bag of worries, hidden truths off your shoulder.
I wish i could write more to my friends since i don't really dare to say it out face to face to them but at least i'm using a different way to let them know what i'm actually thinking or how i feel about certain things and i know they do appreciate it.
I really wish that i've the time to write to them. :)
I guess this is one of the element to keep the friendship going? Just like in a relationship, you've got to spice things up at times.
Start showing your care and concern to your friends whom you've neglected or didn't manage to catch up with recently.
Show that you still care and have not forgotten about them.
