Aw :( well the next time both of you have off st the same time, you should ask him! But I know it's hard because you'll want to hang out with your son on your day off too :/
You can! It's just called "father and son bonding day" on his weekend! lol I've pulled it a few times! "I'm with phillip all day long, he really needs just a daddy day don't you think??" 😉😉
