Drawing Circles

I drew a circle

it was a nice circle

but it wasn't perfectly round

it skewed slightly to the right

so i drew over it

tried to even it out

now it veered off to the left

over and over

I repeated this task

painstakingly tracing my line

correcting flaws

only to create new ones

I just couldn't get it

perfectly round

with even depth of line

and proper thickness

now

where once I had a pretty good circle

slightly skewed

but nice and neat

I have a big ugly mess
