One Promise? (Needs More Work)

Wherever I roam or wonder I ask but one promise All that I ask is that you never will leave It may seem to you little, but i cherish this With you by my side there is much i can achieve There are days I am cruel and others I am kind I don't expect my troubles to take up and go Yet you often find ways that do ease my mind With each other we can learn to watch and grow I am aware that a time may come when you stray Another will attract who is better all round Still if you allow I will wait for this day To ensure your safety with feet firm on the ground
