Let me reach in my memory banks from when I was a Christian and see if I can come up with some to see if they ring true with you.
I didn't have all the answers. People would ask me why bad things happened to good people. I said, Because we choose to do bad things to other people. They would ask me why there are starving people if there is a loving God. I would ask why the US is such a good nation when it wastes so much food while others in Africa starve. We have more than enough to share, and more than enough wealth to help 3rd World Countries. It's like you parents leaving your older brother $20 for pizza. He orders it, eats 3/4, and leaves 1/4 for you and your 5 sibblings, and says, "Mom should have given us more money. Blame her."
They will ask me why there is hell, and I say that I didn't know.
They would ask what happened before the beginning of the Universe. I said that I didn't know.
I was simply Christian, not some wise sage living on a mountain.
As a Christian, one of the problems I had with other Christians was the issue of tongues. I speak in tongues, and have since I was 18. I don't do it for other people when they ask, unless they are simply curious and want to know more. However, people will accuse you of doing something from the devil. They have said that it isn't necessary, which i agree, and while a fork and knife aren't necessary, I simply choose to use them. There is also something that changes in ones Spirit when tongues happens. And its kind of supernatural, and amazing. They will argue that if one doesn't understand, you shouldn't speak in tongues, only it is done in private prayer. They will say it isn't biblical, and I just get tired of trying to justify it, and rarely tell anyone in rl.
I also remember nonChristians being hypercritical, saying, "Look! You're drinking beer/swore," etc. I didn't condemn others, but I think that is what they thought I did, where it be outloud or not, because they have probably experienced that from the minority.
I also God tired of "proving God." I usually said that I can't prove God, but I don't know how not to believe in God. I have since I was very, very small, and would talk to God when I was alone. Because I can't prove it, I simply have faith. I can't prove love is real, and yet, I believe in it.
Finally, I think the opposite was also true. I think people thought I was a priest, very good, they had to watch what they said around me, and it made me really sad, because the thought I was too "sensitive" to hear a swear word, or never had a beer. While I strove to be pure of speech, it was a struggle, and sometimes I just let it go. It's actually pretty hard to offend me.
