Sometimes I get myself in situations where I'm introduced to a group and we are going to spend a limited amount of time together, such as a party. While some people and/or groups are incredibly open and receptive, some don't really care to make you comfortable or to let you into their group. Often the conversations are inside topics and jokes and there are rare interactions with me, making me feel ignored.
I'm not interested in make new friends. Most times I have a friend in common, or I'm new in a quick course, or spending a weekend with wife's work colleagues. I just want to go through one night, day or weekend..
How can I make the time go faster and less painfully?
