Grandmothers don’t always have common sense in the ways of social media, but an Arizona woman’s wrong-way text has made her an Internet star.

Wanda Dench thought she was texting a Thanksgiving invitation to her grandson, but the person who received it was a total stranger, Jamal Hilton, a college student. He was having lunch earlier this week when the invitation showed up on his cellphone. He didn’t recognize the phone number, so he wrote back asking who sent it.

“Your grandma,” Dench wrote back. “Grandma?” Hinton replied, “Can I have a picture?”

“That s strange,” Dench thought. But she dutifully took a selfile (自拍) of herself at work and texted it.

You are not my grandma,” Hilton said, “Can I still get a plate there?” Dench was embarrassed at her mistake, but quickly recovered.

Of course you can, ”she wrote back. “That’s what grandmas do... feed everyone.”

Dench is white. Hilton is African American. The student took a screenshot (屏幕截图) of the conversation and posted it on Twitter, where it’s been retweeted (转发) more than 150,000 times.

Dench didn’t know that Hilton had posted their exchange online. Then her phone blew up. In just a few days, she received more than 600 text messages and lots of voicemail because her phone number was included in the screeshot.

“At first I thought, ‘Well, this is annoying,’ until I started reading some of the people’s texts.” she said. Strangers wrote, “Thank you so much. You’re such a kind person to let this young man into your home.” She said, “I think this may be a little more important than what I thought it was because of the racial tension that’s in the country.”
