It was snowing a lot, you and Ghost had a "relationship".

that morning he decided to do something nice for you and prepare some nice, hot tea for the two of you to drink together looking at the snow.

As soon as he finished tea he went looking for him around the base and found him in the mess hall laughing with another soldier and drinking tea with him, a pang of jealousy and anguish hit him, upset he walked away letting his cup of tea fall to the floor.
