Does using the accidental se structure require the use of the perfect tense [haber (conjugated to item forgotten)+ past participle "olvidado"] or can I use the preterite (indefinido) also?
For example:
Perfect -> Se me ha olvidado la toalla.
Preterite -> Se me olvidó la toalla.
Sounds weird, but just asking for clarification since I didn't see any discussion of specifically using the HABER + Olvidado structure.
Cheers!
