The context of the following conversation is Austin gave Robin reason not to go. The reason was completely valid.:
Robin says Austin told me I should stick around for my sister's childbirth and not go on the trip to the mountains.  I thought that was a valid reason..
The friend responds You can go up to the mountains any time..
Robin responds My sister looks like she's about to pop any minute.  She would want my support..
The friend responds Is this her first child?.
Robin responds Yes, the baby daddy took off a couple of weeks ago so she's all alone in this..
The friend responds You be there for your sister.  She needs you..
