No, they do not! Heck, they cannot even write decent family altogether for a holiday stories.
I get the feeling the writers/producers feel uncomfortable with "mushy" scenes. Heck, a lot of families get together, the meal may be buffet style, with tables all over the place. Or a bunch of non-matching ones shoved together. They did that once at the Pub, but we rarely see families sitting down together, or just a lot of friends, some related, most not (tho seems everyone in Salem is related in some way or other. LOLOL
