I second the question matter to whom? In this case I'd say no though. Weight is just a number, it's subjective. you can have 5 people that weigh, say, 130 with all 5 of them being at completely different levels of health.
Someone tall might be underweight, someone short may be overweight, someone 5'5 (falling right in the middle of normal by bmi chart) could have a high body fat %, a low body fat%, or a normal body fat % depending on their muscle tone (similar to you and your friends situation)
Ignore the number on the scale and worry more about how you feel about your body, how your clothes fit, etc
