Dear Tom,

    I'm glad to hear that you are considering make up with Peter. If I am you, I would consider a bike as a birthday present for him.

    As far as I know it, Peter is always in poor health so he can take more exercises by riding a bike to build up his body. In the meanwhile, you can often go outing by bike together, which is helpfully in rebuilding your friendship. Beside, taking a bike is an environmentally-friendly means of transport. It's convenient him to get around as well.

    Apart from giving him the gift, you can also adopt other means, such as traveling, seeing a movie, having dinner and going shopping. No matter how you do, being sincere was the most important. I really hope that you can be good friends forever.

Best wishes!
