I have an honest question. As a skinny person, I try to always be friendly and look welcoming when I see a large person looking for a seat but it doesn’t always work out that way. Is there a way before boarding I could alleviate some of the anxiety of a larger person and let them know somehow I would welcome them sitting next to me so they don’t have that extra worry at least DURING the flight? Without insulting or making them feel bad or awkward?
