I actually think it's about someone who has been in prison for the last three years and has been wanting to get out. However, now that he actually IS getting out, he is afraid of the freedom and the possibility of making the same mistakes again (not being able to change no matter how much he wants to). He is afraid of the responsibility the freedom brings, as he's used to being "safe" in prison where he can't commit crimes. Freedom means that the choice is his, he has to resist all the temptations he faces. In prison there were no such temptations so it was easier to act in a non-criminal way, but after getting out he is in the same position as he was before, so why would he not go back to his old ways? Outside prison there are also people who know what he's done and will treat him as the person he was before: it is more than possible and easy to be that person again (even though he doesn't want to). The mum is understanding and tries to encourage the son. He loves his mum very much and wants to make her proud, therefore trying to change for her (although being unsure of whether or not he can). She points out that in order to make things better he has to change for himself, not for her.
