11. Liquor
Ed had never been too fond of alcohol in general. In his line of work, and with all of the enemies he'd made, it was never a good idea to do anything that might inhibit his motor functions.
However, when a group of fellow soldiers insisted on taking him out and getting him smashed on his twenty-first birthday, he didn't argue and Alphonse insisted anyway.
It wasn't until the third pitcher of beer came that Ed noticed the solemn figure at the bar nursing a tumbler and, with alcohol-induced bravado, he made his way over to the man.
"It's my birthday y'know. Come celebrate with'me."
Mustang just raised an eyebrow at him, so Ed kissed him and repeated himself, "Come celebrate with'me."
They didn't stay at the bar for much longer.
