Some things are just not worrying or bothering about, in fact doing so will just use up precious energy that could be used for things that are so much more exciting. If you were having a great time and then another person came along to flatten that mood with their negative projections just understand that their mood is just a sign of how fantastic your life is.
Be kind with your responses and then just cross over the road, be on your merry way, and spread your joy to those who are ready to receive. They are unlikely to follow as they are already stuck in the mud. This is the time to move forwards with your life and experience a positive outcome. Allow ideas to flow and keep the mind enterprising and filled with fresh inspiration.
This is the time to fly so JUST DO IT!!!
