I'm not really sure when it comes to work but sure if there are more people, more pressure basically will be on me. Also whenever I'm with my friends and try to explain something, if I stutter, they in 75% of the time either ignore what I say or talk what they think disregarding anything I said. I hate this so much and only happens when we are in a group especially above 3 people. I always end up distancing myself further from such people but sadly this always happens with any group of friends I had.
