No, especially with long-time friends, they might sometimes glance at one another casually out of curiosity or habit, but it's usually not a big deal. For close friends who grew up together, there's often a level of comfort and trust, so such situations tend to feel normal or nonchalant ¯_( ° ʖ °)_/¯
