A Faulty Friendship

I look back,

to the days that we were the closest of friends.

We both acquired new friends,

and we sooner or later drifted apart.

Now you won't say a simple "hey",

or an easygoing "goodbye".

I wonder,

"Was it my fault?"

"What did I do wrong?"

I must have offended you.

I'm not sure how,

but the best thing would be to talk it out,

don't you agree?
