Sometimes things get tough, and we rely on the people around us to help out.

But as all empathetic people know, this should never be an expectation, because people have needs of their own – instead, the kindness of others is something to be grateful for.

So when the guy in this story was asked to cut his sister’s friend’s lawn, he was sympathetic to her situation as a single mom, and gave up some of his precious time to do so.

However, when he saw the grass itself, he realized he’d been taken for a fool.

Read on to find out how he ended up being framed as the bad guy.

AITA for not cutting my sister’s friend’s yard

A while back, my sister asked me if I could cut her friend yard as it was getting tall.

For context, her friend is a single mom of one child, and lives in her own home.

I agreed, then asked her for the details – where she lived and if she wanted me to cut front and back.

She told me front and back and that she wanted it cut asap because she already got a notice for it to be trimmed.

But when he saw the yard, he was in for quite the shock.

She proceeded to show me pictures and her front yard was outgrown, but not too bad.

However, her backyard was hideous – the grass was almost to my knees and I’m a pretty tall guy.

I was a bit reluctant but still agreed.

After loading my push mower and weed eater to my truck, I texted my sister that I’ll be fine with $30 bucks for doing it.

And this innocent action caused the whole kind act to go sour.

She then proceeded to get mad at me and called me selfish for not wanting to help her friend because she had a kid.

I told her that she was her friend and not mine, and that it was a reasonable price for her outgrown lawn.

She then told me to forget about it, and that she will find someone else to do it.

AITA?

It’s one thing to do a favor for a loved one.

It’s a whole other thing to be roped into helping someone you don’t know, with a mammoth task – and the expectation that it will be done for free.

$30 is a more than reasonable price for such a hefty job.

Let’s see what folks on Reddit thought about this.

This person was totally on his side.
