What can you take but not give?
You can take the time to do something but you can't give it
What takes hours to do but it’s over in an instant?
I think the concept of time is that time seems to go fast for us (hours to do) but in the span of for e.g. the universe our lifetime is nothing
You can get it but never save it.
You decide how to spend your time but once your time has run out it's over you can't save up time
What gives you sight without seeing?
I think this refers to time being a concept that humans created we are the only ones aware of time.
Run without legs.
time runs by, but has no legs.
Travel the world but never leave.
Time for humans is a concept around the world but as stated before we are the only ones using it on our world.
The past is now. The future is history.
We all have been there.
we all exist in this timeline.
time is free (unless your working :p )
You can do it with family and friends but they never see what you see.
you can spend time with family and friends but they can spend it how they like.
Thousands of memories but no pictures.
in one second of time going by millions of people have memories.
