Hi reikipowee, it is only what you fear that can manifest. The other person is simply fearful themselves and so best to try not to allow yourself to be influenced. Pivot and know that you are safe and you will be.
You could also try to work on yourself to not attract negative people or at least not to attract negativity from them towards you. ie do Abrahams segment intending and say affirming things (to yourself) like for example " Wouldnt it be nice if ...', "wouldnt it be nice if my friend lightened up a little .." or "wouldnt it be nice if ... my friend started to have more faith in me ... " find a 'wouldnt it be nice if .... " statement that suits you and that starts to improve your expectations of your friends and entourage. Soon you will be amazed that they start to show a more positive side while around you. Or simply be grateful for this person/friend despite their negativity and your gratitude will undoubtedly give them blessings and grace.
But first and foremost know what you want to do and be positive about it and enjoy it knowing that you are always safe and happy !
love and light Gen
Stop fearing what the other person is thinking.
At the end of the day, you are only actually responsible for yourself, and you are only under the law of your own consciousness. If the event is about YOU, but you are not worried about it, then the other person's fears won't be strong enough to override your positive beliefs.
