Thursday Thuck Up

Please excuse the lame title, I couldn't find any word starting with "th" or "t" to truly describe the pickle I've put myself in.

My current weekend plan is as follows

Saturday Evening
Attend a 21st an hour south of where I live. This involves obtaining a swag to stay the night.

Sunday
Mother Dearest's Birthday. Drive home in the morning to spend the day with family.

Issues at present

One
I agreed to visit a friend, half an hour north of where I live tonight to borrow their swag. I also had planned dinner tonight with the immediate family, my cousin and her partner.
Meeting my friend at 7.30 (ish) and dinner is at 7.00.

Two
I have yet to get Mother Dearest a gift or three.
Tonight is late night trading and I can't shop.

Three
Mother Dearest is attending a ball in the very near future and needs a dress. We are to go shopping on Saturday. My cousin (the one coming for dinner) is getting married, and I agreed to go shopping with her for the invitations on Saturday.
I can't shop with both of them at the same time. (Yet to figure out the whole :Two places at one time idea shown in Sliding Doors:)

Four
I am yet to get Mother Dearest a gift or three.
I have left myself 0 (zero) hours free to go shopping for a gift.

OH THUCK!!!

Guess I'll be leaving work early today then huh?
