My mom always took her coffee black, so did my grandma, so I think it imparted onto me. For me I like the bitterness, when I take a sip of my morning coffee and it hits there's nothing like it.
Over the years I've tried to get into sugared coffees and I still keep coming back to black. Although every now and then iced coffee with creamer and sugar is a good treat.
I was like 13 and I wanted to be more adult. Couldn't finish the first cup, after a week I was able to choke it down, by 2 weeks I thought it was okay, by a month I wouldn't have it any other way.
