Anime suggestions please!

You might get an idea about the kind of anime I'm looking for by reading the following examples..

AnoHana (pic)
Clannad
Angel Beats
Nagi no Asukara
Kokoro Connect
Sakurasou
Ano natsu
Little Busters
Sket dance
Chihayafuru
Chuunibyou... :P
Haruhi Suzumiya... XD
Free! ...maybe?

(the plot! the plot!!)

Technically, an anime that revolves around friendship... that is capable of bringing me on the verge of tears...
Also, those who've seen Mekakucity Actors, I love the relationships between the members of Mekakushi Dan... So, something similar to it maybe...

NO sport! NO action! NO horror! NO ecchi!

It would be better if it's a short anime and please recommend anime that are worth watching only!
And please keep the 'list' short...

P.S. - just so you know, I've watched almost ALL the mainstream romantic anime.. if u r planning to suggest any... and that's NOT what I'm looking for...
