Halloween party

It was Halloween weekend in the early 80s. My mother said we were going to a Halloween party at a friend's apartment and asked what I was going to dress up as. I asked her if I could use an old bed sheet and go as a ghost. She said ok as long as it's an old one. I cut out two holes to see out of and one for my mouth, and colored around them with a marker.
It was hot that year so I asked if I could just go in my under pants. Mom said to take some clothes with me so that when I get tired,I could change. When we went to the apartments there were parties everywhere. We went to her friends apartment and she met up with her. Being mostly older people there I asked if I could go trick or treating. She said ok but don't go out on the streets. I went down stairs and seen a party by the pool, and desided to check it out. There were a few guys my age and we goofed around some. After a while I was thirsty and a little tired. Someone asked if I wanted a beer to drink and said sure. I gulped it down and they gave me another one. After drinking it my head started spinning. Heading out of the pool area an older man asked if I wanted to sit down, I said yes I think I should. He pat his lap and said to take a seat. After a few minutes he asked my name and where I lived. I told him my name and said we were visiting a friend here. Than he asked my age,I told him and his face lit up. The person in charge of the beer came by and the man said he wanted two. After the guy left he handed one to me,and said to sip on it.
Feeling relaxed I laid back on him and he put his arms around me.
