let's speak metaphorically.

just because you close one eye, doesnt mean you see only half the story.

so sometimes, it's better to close both eyes.
but as someone logically pointed out, you cant see the walls in front of you.

and with one eye, you can still be forewarned.

but it is better to be fully blind for some situations.

because if you weigh having 6/6 vision and losing you, and being blind and having you, i guess i'd take the latter anyday.

i can only hope that when i crash into the walls, you will be there to comfort me.
because you are the one i would give up my sight for anyday.
