Have you noticed how some people you consider to be friends, are always too busy when you really need them?
I’d suggest that those friends who you have found are not there for you, when you really need a friend, are not the friends you may want to rely on.
We all live extremely busy lives these days (even if we are spending more time at home), and so when a friend finds time to message you or call you, even though you know they’re busy, just to ask how you’re doing, you know you have a good friend.
An even greater friend is one who, no matter what they may be doing, or may have planned, they will literally drop everything, and be there for you when you need them. They are the friends we should call true friends.
