Ah! They are all dressed up and going out somewhere: Mom is looking 70s fashionable in a maxi dress with a solid white top and black patterned skirt, and Dad has on a suit jacket and a tie.
You know ... when Mom went out with Dad, she could pretty much count on the fact that he wasn't going to drink so much he would throw up, act immature, or do anything illegal. That he would be the charming guy everyone wanted to invite to their parties. That he could talk to anyone about anything (and boy oh boy do I have a story about that, lol, from a 90s wedding Dad and I attended together!) and so he never was someone you would bring to a party and have to babysit, is what I'm saying.
Really, they should clone him for today!
