"I long for you all, including the mutt!"
Translation:Mi sopiras ĉiujn vin, inkluzive la hundaĉon!
PIV shows it used three ways: al/pri/je. As always, it's possible to switch between je- and -n forms.
They all seem very similar, but if I have to guess at the nuance, they mean:
"sopiri [pro la manko] je" -- In the Lernu! grammar this is called je of "manko/abundo/sopiro."
"sopiri [pensante] pri"
"sopiri [kun sento] al"
