It will be effective, as long as you choose the gift carefully, leave a message or say it to him carefully. The situation at that time must have been that you both encountered unpleasantness, so you should be able to apologize to each other or express your regrets afterwards.

Having a bad temper is a very bad thing. You must start to change your thoughts and actions bit by bit. When you want to lose your temper, shut your mouth immediately and imagine that your mouth is stuck. You can't speak out and lose your temper. When you don't speak out, ask yourself who you want to hurt by losing your temper? What's the point? As long as you can calm down, I believe you will no longer be so impulsive.
