Lack of Communication - seriously. Know how to communicate your feelings and needs, otherwise there is no way it'll work out.
Sense of Humour - everyone has one, just some are way more different than others. As long as we have somewhat similar senses of humour, all is well.
Physical Intimacy - I don't expect it right away and I'm okay with waiting. But it's an important part of any relationship, so finding out if we are sexually compatible is a must sooner or later. That would be something we would have to communicate about!
Must like Waffles - I looove waffles, and expect the same. No pancake loving motherfuckers here.
Shared Interests - a must. Obviously we're going to be interested in a lot of different things, but having some common interests is necessary! We won't enjoy all the same things, but at least be willing to try them out to see if you enjoy it too.
Pancakes - I guess it's okay if you like pancakes.
