We might have similar experience.
You two both miss the other. You two both want to know how he or she is doing. You two both expect news from the other. You two both are involved somehow.
But it’s quite a long time since you two met the last time. Contact between you even disappeared. No meeting, no talk, no phone call, no e-mail, no cell phone short message. Only missing exists. Even though the physical distance of you is not far.
By this time, distance of your minds has gotten kind of remote.
At least one of you is too lazy to think about the other one still exists.
Gradually, you two accept the other’s disappearance.
You ignore it.
Even if one of you wants to own the other again, just like before, it’s impossible to get back.
Then two strangers come out.
Maybe, some day, you would need time to remember the other’s name.
While you are trying hard to recollect that smiling face, you must ask, “Are you alright?”
No matter where you are living, next street or another city.
