Answer: Television it's a portal to another world which you cannot enter. Only you can see it but It can’t see you.
I got hot but I never sweat, I cook food but I am not a chef, I have a door but you can't enter me, I have a light but I am not a lamp. Who am I?
You can kill me but you can't eat me. You use me every day. I am always there. You cannot get away from me. If you can't manage me you must be disorganized.
What am I?
I am all around you, but you cannot see me. I have no throat, but you can hear me. Valued during summer but despised in the winter. What am I?
