Communication, common interest and having fun is the biggest factor.
In order for friendship to grow, talking is a natural ingredient.
If you do not know the person, their likes, dislike, belief's, values, wants, needs and share your own how can you find common ground? Take things slow, grow your friendship and romance will fall into place.
Good things take time, and last forever! 1.
Talk to your friend daily.
Do you constantly chat at least once a day? By taking the time to chat to him/her once a day, not only are you taking the time to get to know one another you are also showing him/her you have an interest in them.
Even if they do not always respond, do not take it to heart.
Sometimes showing lack of interest is their way of letting you know they are into you too.
This is not always the case, but in most times it is.
2.
Show an interest in them! By showing them you care about what they are up to in a run of a day.
What movies they dig, and what music they hate.
You are letting them know you dig them! 3.
Have fun, flirt a little bit, and be yourself.
If they like you for who you are it is easy to grow that friendship into something more.
Never be something your not, if you over do something it could turn them off.
4.
Do NOT always respond.
Responding right away makes you look desperate.
Take time even if its just a couple of minutes and make them wait for a response.
If they are interested this will make them curious as to what it is you are doing and who you are talking to! Be patient! Growing a friendship into more takes time, do not rush it.
Rushing things will make your hard work fall to pieces.
Let it take its natural course.
