it depends on the person's nature ofc,
like me, i dont find anythin funny when something serious goin on n thats anything related to me, with my work, cz im sorta realistic n dislike anything going off track with me, may it be studies, any kinda prblms with frns, family matters, etc, thats something im serious with & wud not like anything funny in there from anyone...until they get all settled....
buh u call it selfish-ness or sweetness? idk,
if something srious is goin on with my frns or sumtyms durin a very serious fight between my youngsters [sibs.] lol so yeah i do crack up with my funny languages expression lol n try to lighten the mood before it reaches to something freakin serious or maybe be optimistic n help them sort out stuff....
