First impressions are not the end all or be all. Sometimes you may feel nervous when meeting someone new for the first time and it may not leave the best first impression as nerves often cause many people to be tongue-tied and unnatural. Also, if you are having a bad day or not feeling great you may not be yourself. Others may be in the same boat, so it is good to give them the benefit of the doubt and not decide right away whether they will make a good friend. Chances are, people will also extend the same courtesy to you—so don’t be too hard on yourself if you let your nerves get the best of you.
