Do i search to much behind it?

This Virgo friend of mine and i are ok
again after our many fall outs.
After our last fall out he blocked me on WhatsApp and never unblocked me again neither did i.We mostly chat through Viber.
But that is not the issue, yesterday we talked through the phone (viber) i thought he hanged up on me but well you know Viber also have issues [so i asked him texting on viber]why he hanged up on me? He said he didn't so i said are you sure? But i wasn't even serious when i said that. he said whatever and said nothing so i send him a kiss smiley and went to sleep. Then i heard nothing from him so i thought he might be angry/pissed off what i've said however it was a joke. So i called him up after lot of hesitation and asked him if he was angry at me his reaction was noo i'm not angry at you there is nothing wrong it is ok. So part of me is glad that he isn't angry but he is ''offline'' (last seen on) on viber and i wonder why he did that? I know when he goes on holiday he do put his viber off so it is possible he went somewhere of busy of do i look to much behind it why he did so? Or do they also react like that after they have talked they need some space?

...thinking he's just off doing Virgo things.

SirHorns what kind of Virgo things lolz
