Orphans and Broken Couples

Listen up, buttercup. This joke is playing on the double meaning of "see each other". Orphans can't "see" their parents because they're dead (duh!). And ex-couples can't "see each other" because they broke up and don't wanna hang out anymore, you simpleton. It's like, a sad fact mixed with a relationship problem. You probably don't get any of it, judging by your brainpower.
