Its common in Christian relationship for one (especially guys) to blush and crush at the other in the private. Especially; through calls, chats and messages. Sometimes, including when they hangout alone.
But when they are in the presence of igwemmadu(other brethren),they tend to act like they never knew the other nor have any interest to do so, sometimes even avoiding them in the public.
These attitudes is very wrong.
Friendship exist when two or more persons acknowledges a sense of (mutual) relevance and developed a sincere respect for (each of) the other.
Identifying with your friends in the public shows you are proud of them as well as the relationship. True friends should have a sense of mutual privilege to be with each other anywhere.
The contrary could have a lot of interpretation; like you are trying not to give other friends the impression that this is your favourite. Or your friend is not good enough…
