Me and my husband were feeling nostalgic a couple days ago, so we logged into our old facebooks and YouTubes to look at our old stuff. And we had to use old emails to do that. Then last night I opened my phone and I had my old email on my gmail app. But I haven't used it since that night. Would me logging into my old YouTube do that? He swears up and down that it doesn't but I haven't used that email at all on this phone besides that one night. Can someone give me an explanation???
