It’s always nice to be helpful, especially to kids.

But as anyone who has ever had a little kid knows that once they reach a certain age, they love to do everything themselves (no matter how long it takes).

And in this story, one girl’s efforts to lend a helping hand backfire.

Let’s buckle up.

AITA for helping my boyfriend’s sister buckle up?

Okay so today me (15f) and my dad (43m) gave my bf (15m) and his sister (9f) a ride to school cuz their mom’s car is being worked on.

We pulled up in front of their house and my bf came out with his sister’s booster seat and put it in our our car.

It’s nice of these teenage lovebirds to help each other out.

Then he got his sister and they came out.

She hopped in her booster seat and tried to buckle up but she seemed to be having trouble.

She kept trying to buckle up but couldn’t seem to do it, I eventually just told her,  “Here let me help you with that.”

I took the seatbelt from her and buckled her in.

Seems like a nice enough gesture, and a safe one at that.

I said, “There you go. It can be hard to buckle up in a car you don’t usually ride in.”

(I’m guessing that’s why she had trouble I can’t think of any other reason).

But tonight my bf called me really angry saying that his sister is very upset because I “treated her like a baby. “

Uh-oh, here comes the backhanded backlash.

He said that his sister said she can buckle up herself.

She’s not a baby, and I just did it to be a jerk.

I told him I just did it to be helpful and help us get going quicker (it was pretty cold outside) but he said she insisted that I was just treating her like a baby to be mean.

Seems like a stretch, since seatbelts are meant to protect.

He seemed pretty mad at me and I didn’t mean to upset his sister but I’m wondering if I did something wrong cuz he’s so upset.

AITA?

What do you think?

Was this a friendly gesture or an infantilizing move?

Let’s check out the comments.

To buckle or unbuckle?

That is the question.
