It is definitely so awkward when you forget someone else’s name and that someone keep on calling you by your name. So what should you do when you can’t remember someone’s name?
When you are in the party and you are surely familiar with a certain person but just could not remember his or her name. If he is far enough from where you are, confirm his or her name with someone who could know him or her. If he is near to where you are, just smile and go with the flow then bring reinforcement in some other friends.
Or this is what you ought to do, bring a friend with you and introduce your friend to that person; this person might go for introducing himself to your friend. Once this is done, do not forget, ever again of his or her name otherwise you won’t have any way at all to get his or her name.
