Feeling uncomfortable with a buyer.

Hi everyone, this is my first time selling on Facebook marketplace and I’m listing my TV, this woman is interested and says that her sister is going to pick it up because she gave birth a few weeks ago… and then.. SHE SENT A PICTURE OF HER NEWBORN BABY for no reason.

I have no idea if this woman is playing around or not.. I told her we can meet at the Walmart parking lot next week, and now she’s asking me if she can pay me now (with Zelle or Venmo) instead of in a week with cash. She also wants me to list the TV as sold.

Please let me know if I’m just paranoid or if this is normal LOL

I’m so confused if I’m getting played or is it because I listed it for $60, because the way she’s typing is a little weird I’ll copy her last message below :

“Okay..Can you please mark it as sold now,I’ll pay it now to secure it cause my a sister doesn’t have to the cash to pay and hasn’t planned on a sale. It’s all on me ok..Do you have Zelle or Venmo so I can make the payment now”
