"I don't know if I could go vegan. It's just so hard".
Alternatives now exist for literally everything ever. Go buy a vegan alternative. Any ingredient from milk to butter to sausage has a vegan alternative.
Just do a search for a recipe that is "vegan [thing you were going to make]". Literally whatever. Pumpkin pie. Chicken stir fry. Mashed potatoes. Look at ratings and comments.
Protip: If you want to skip the long preamble on recipes, ctrl+l for "print" and usually you'll land on a "print this recipe" button which will take you to a new page without all the crap.
Suggest to your friends a place with vegan options. HappyCow is a good place to start. If you end up at a place like Applebee's or something and don't want just a plain salad with oil and vinegar, just order a plain baked potato with A1, or ask the wait staff if anyone in the back has a suggestion. Or go to a grocery store and pound some clif bars on the way.
It isn't hard at all, unless you don't actually want to do it. Then it will be impossible by definition.
