Haiku string - my family gone

(I have not posted for a week. Life out of balance. Here is a haiku string written on an airplane flying to St. Louis this last Tuesday.)

Missing my father
in the early days of May.
First beers outside back.

Wanting my mother.
Her little one's little ones
miss her this Springtime.

Dear little brother:
You left in early Summer
Not March as they say.
