My husband have eyes surgery appointment today

My husband and my father in law went to St.Louis because my husband have doctor's appointment today for eyes surgery. I'm scared for him to have eyes surgery but he said he has done it before. He's not scared to have it and he's happy to have eyes surgery so that his eyes will be fix and back to normal. So, I just let him to have it. They left home very early this morning and I think they're in St. Louis now but he said he's eye surgery is not until 12pm. So, they have time to roam around there for while. I'm sure the surgery is going to take so very long and he said they won't be home until 8pm tonight yikes. Hopefully, his eyes surgery is going to be ok and everything will turn out good.
