On Friday night my good friend invited me out for a drink, she'd also invited another friend "Sarah" (I don't know this friend too well as I've only met her 4 times)
We got a taxi and had one drink and then Sarah just changed, knocking over her chair, stumbling, talking rubbish, grabbing our glasses of wine. Turns out she'd been drinking practically since she'd woken up that day.
The whole night I felt like me and my friend were babysitting. The night really was not fun.
Apparently she does this a lot (drink excessively) and have to be looked after. In the couple of times I've met her shes told me herself what a lightweight she is.
I just think its really selfish behaviour that if you are a lightweight you would on many occasions drink excessively and then expect to be looked after and not allow others to have fun.
