Odd man out?

I was reading through 1 Corinthians 13 ( for those who don't know this is known as the love chapter) and noticed a verse that kind of stood out from the rest. “When I was a child, I talked like a child, I thought like a child, I reasoned like a child. When I became a man, I put childish ways behind me.” (verse 11). At first this doesn't seem to fit in with the rest of these verses. I wonder if Paul's trying to say that this kind of love requires a level of maturity(?) I'm not quite sure and would love to get discussion going on this.....
