Answer:
Though I am only two words I have thousands of letters in me
I run around the streets all day. Under the bed or by the door I sit at night, never alone. My tongue hangs out, waiting to be fed during the day. What am I?
The more of me there is the less you see.
I am just two and two. I am hot. I am cold. I am the parent of numbers that cannot be told. I am a gift beyond measure a matter of course. I am given with pleasure when taken by force.
you need thousands of me to create a digital image.
Whoever made me don't want me. Whoever bought me don't need me. Whoever use me don't know me.
