Well I'm really worried now about my Friend on Skype now?

He has not answered for 5 Days and I am worried as all get out.He usually answers back and for him to not answer back is weird.After I posted my previous question about this it has been 2 days since then.So this is sort of like a Update. I don't know if he's on vacation, moved away,gone completely, or blocked me.I'm worried that something happened to him but I'm not sure.And there's a yellow light beside his name but I don't know what that means? What should I do?

maybe his internet doesnt work, maybe he forgot his password. but I wouldnt think he blocked you. just ask him somewher else
