Can someone let me have their old minecraft account?

I would really like if someone with a minecraft account that they don't use anymore would lets me have it

No.
But there's a launcher (sorry still on 1.5.2 and will never update). Search minecraft launcher anjocaido on Google (ON GOOGLE!) and… Just find any file, download and clean it and there you go!
In the startup, just type a random name. No login account needed!

Even better just type in mineshafter (runs on 1.7.9)
