Ha! Brilliant! My girlfriends son is 21 and ive been a father figure to him since he was 9, a few days ago he asked us if I would take him to Amsterdam!!! Just me and him, no mum! She's cool with it and I happy for me to take him and show him the 'scene' the only awkward feeling for me is not wanting him to see me giving attention to girls out there even though there won't be anything behind it!
In the same way that if im out driving with him, im actively avoiding rubber necking at hot women as it feels disrespectful to him!
