Green Lantern
The pain of loss never truly goes away. John had known that for the longest time. While he and Bruce were never the best buddies but they were good friends and worked together reasonably well. He also had helped, in his own strange way, him and Shayera to sort out their relationship and get them together again. Now they were married and going to have a baby.
He was inside his room and he was getting ready to go to bed. He then noticed that there was an envelope on his dresser. He picked it up and it had one word on it, John. He opened it and read it.
Dear John,
Do yourself a favor and don't take what you have for granted. Shayera's a good woman, angry, but good and she's good for you. DON'T lose her.
Anyways, John, thanks for helping me get together with Diana. I wouldn't have had that if it wasn't for you. You helped me make my move and it gave me the most happiness I've felt for the longest time. Thanks for that.
Also thanks for just being a friend and being there for me. On the field and on the Watchtower. And you'll make a good father just don't treat them like soldiers. Treat them like 'I love and I know what best for you even if you don't understand'. Truth about boys, they're exhausting and will wear you out. It's just in their nature. Girls, I have no idea about so you're on your own with that one. Take care, John.
Your friend,
Bruce
P.S Boys' main two weaknesses are candy, mainly chocolate, and video games. Threaten to take them away and they'll do whatever you say. Trust me it works every time.
John reread the letter and smiled a little bit. Leave it to Batman to give him parenting advice.
