How to take better photos of my wife

If this isn’t the right sub please delete. So my wife and I are going on a trip to Europe in a few months. And just like most millennial men, I’m terrible at taking photos. She always gets upset about the angles, lighting, etc. is there any advice anyone can give me and pointers on getting the best quality photos of her and practice now that way we have good photos on our trip? She jokes and says we will be in our 80s and have like 0 photos of each other lol.
