Should I go out tonight?

It is really your decision. But, assuming that you are in the western hemisphere, it is still early enough to put last night's outfit in the wash, walk to your friends and get your makeup, walk back and then shower while your clothes are drying, in time to go out tonight. Could the people who invited you out pick you up? Or drop you off afterwards? That would save some of the taxi fare for either more, or better, drinks.
