Most Helpful Girl
I do not find it any different than being with Just anyone, whether it is mom or dad or who it is, if even one would Say: We have to go and pick up the groceries.
Just a little Pronoun that is Now, after all of these Years... Being questioned?
I would be more concerned if he Said: My buddy here and I 'Got to go.' Even if you both are not yet a 'Couple,' 'We' is not bad, just a little term used when meaning 'US.'
Good luck. xx0
