My FI's younger brother (in the WP, if that makes any difference) lives with his mom and stepdad. FI's mom took her husband's last name, so younger brother has his dad's last name.
How do I write this in the address? I feel weird writing "and family" (which I am doing for others, since I didn't find the inner envelopes until this morning, halfway through my list and I got postage according to the weight without the inner envelopes) because he is 17, not 4.
Do I do it anyways?
Or should I put:
Mr. and Mrs. Sylvester Stallone
John Doe
address
address
Or should I just give him his very own invitation?
