We’re never going to be separated... we’ve been dealt a weird hand but we just have to deal with it

– sometimes that’s as big a deal as being stuck to your sister.” The Trump government recently tried to remove the programme that allows the family – and other immigrant families – to stay in the US. The deferred action programme means immigrant families can stay if their children are having medical treatment. Currently, they have to renew their right to remain every year. They finished high school, Carmen learned to drive and at the second attempt. Lupita says: “My dad wouldn’t let me drive after I almost crashed into something.” And Carmen explains: “I have the right leg and I’m a little bit taller than her. We tried letting her hold the steering wheel once. It didn’t really work.”

Lupita adds: “I put the turn signals on. That’s pretty much it.”

The two have loved animals since they were little and see their future as running an agriculture business.

After going to an agricultural high school, they’re now at college two days a week and hope to study in the veterinary field.

“We’ve both been interested in animals since we were five” says Lupita. “But because of certain physical issues we’re going into vet tech and then hopefully we’ll go on and get a bachelors in animals science.”

High school was a good time for the girls and they made close friends.

And one teacher in particular, Mr Davenport, made the whole thing go smoothly. The twins are seen saying a tearful farewell to him in the new documentary. Carmen says: “There have been obstacles physically. But he never said anything or made us feel like there’s anything we couldn’t do.”

For now, lockdown goes on. The girls hope it will be over in time for their 20th birthday in a couple of weeks. They want a party, to go out to the park, hang out with their friends or go out on a boat with their dad.

They’ve passed the time watching Tiger King and listening to 90s music. Destiny’s Child is a favourite.

The two spend very little time reflecting on being conjoined.

These days there are very few arguments. If the worst comes to the worst they can put separate headphones in.

Lupita says: “We worked it all out a long time ago.” Carmen adds: “We are two peas in a pod.”

Two Sisters, One Body airs on Sunday at 9.15pm on Channel 4.
