An environment that reinforces drinking?

My mother drinks too much. Way too much. She usually shares a bottle of wine with my dad before gulping down an entire bottle of Jagermeister. She claims she can hold the alcohol but she becomes downright mean, starts slurring her words, suffers from memory lapses, starts flirting with men when she’s out and doesn’t get out of bed until 4 o’clock in the afternoon during weekends.

Now what I’ve noticed is that people see this as one of her lovely little quirks. During special ocassions she actually receives bottles of Jagermeister and people mock her about drinking too much in the most endearing way.

Why? Last time I checked an intake of too much alcohol is dangerous. What are your opinions about this?
