A little while ago I ended up in some fisticuffs with my Ex Missus' brother. I won quite comprehensively. However, last night me and the current applicant for Mrs BB were out for a quiet drink when I was accosted by his 4'11'' 7 stone girlfriend. She walked over and poured a drink over me and offered me out. I declined. If she had physically hit me I would have been able (with a clear conscience) to lay the cow out cold. However, as she just drenched me and stood there gobbing off, i was pretty well fcuked. What is the correct etiquette on this occasion ??
